At present, the marketization level of China's pharmaceutical intermediate industry is relatively high, showing characteristics such as a large number of small and medium-sized enterprises, concentrated production areas, stable business scale, low level of process technology, and serious product homogenization. The difficulty of developing new products is increasing, and the competition for traditional products is also becoming increasingly fierce. In addition, the impact of national environmental protection policies has led to a decline and slow growth in the market size of the pharmaceutical intermediate industry. In 2018, the market size of China's pharmaceutical intermediate industry was about 2017 billion yuan, a year-on-year decrease of 24%. In 2020, the industry resumed positive growth.   In the early stages of the development of the pharmaceutical intermediate industry, due to small investments and lower profit levels compared to ordinary chemical products, a large number of small chemical enterprises entered the pharmaceutical intermediate field, resulting in rapid production growth. From 2012 to 2016, the output of pharmaceutical intermediates in China continued to grow. In 2017, the output of pharmaceutical intermediates declined due to the tightening of environmental protection and safety production policies and industry adjustment. It will not start to grow again until 2021 due to the impact of the COVID-19. In 2021, China's production of pharmaceutical intermediates was 10.32 million tons, unchanged from 2018.   Due to the similar production methods of pharmaceutical intermediates and chemical raw materials, Chinese chemical raw material manufacturers usually also produce pharmaceutical intermediate products. The Chinese pharmaceutical intermediate industry is relatively scattered, with most enterprises having relatively small scales. In the future, with the implementation of environmental protection and safety production supervision policies, enterprises that cannot meet green production requirements will gradually be eliminated, and the industry concentration will increase. The company with the highest market share is Prolo Pharmaceutical, with a market share of 4.09%.   Prolo Pharmaceutical is the enterprise with the highest proportion of pharmaceutical intermediates in China, and is a leading player in the industry. Its main products involve multiple fields such as anti infection, anti-tumor, cardiovascular and cerebrovascular, psychiatric, and veterinary drugs. It was listed on the Shenzhen Stock Exchange in 1997, and according to data, the company's revenue from intermediates and raw materials has been increasing year by year. In 2022, Prolo Pharmaceutical's revenue from intermediates and raw materials was 7.787 billion yuan; Heryi Pharmaceutical was established in 2007, with its main business being the research and development, production, and sales of advanced pharmaceutical intermediates, active pharmaceutical ingredients, and related products. In 2021, it expanded its CDMO business for chemical active pharmaceutical ingredients. The main product categories include anti allergic, anti thrombotic, antioxidant, gastric ulcer, antiviral, antipyretic and analgesic, and UV absorbers. From the perspective of product structure, pharmaceutical intermediate products are the main source of revenue, with a revenue of 190 million yuan in 2021. In addition, the revenue from UV absorbers and other products in 2021 was 11.43 million yuan and 7.64 million yuan, respectively, accounting for 5.47% and 3.66% of the main business revenue. The pharmaceutical industry in developed countries in Europe and America started earlier, but with the continuous development of global productivity and the deepening of international division of labor, pharmaceutical companies in developed countries in Europe and America are focusing on the research and development of innovative drugs and market development, which is accelerating the transfer of the pharmaceutical intermediate industry to Asian countries including China and India. In order to meet the continuous development of the pharmaceutical industry, China's pharmaceutical intermediate industry will move from the traditional mode of low-level repetition, lack of innovation, and extensive production to the direction of innovation upgrading, high quality, and high level. With the advancement of research and development work and the accumulation of independent intellectual property rights, the product added value and process complexity of pharmaceutical intermediates will continue to increase, becoming a strong guarantee for the development of the pharmaceutical industry.

Scientific use of SCP model SWOT、PEST、 Regression analysis, SPACE matrix, and other research models and methods are used to comprehensively analyze the market environment, industry policies, competitive landscape, technological innovation, market risks, industry barriers, opportunities, and challenges related to the pharmaceutical intermediate industry. Based on the development trajectory and practical experience of the pharmaceutical intermediate industry, we have carefully studied and compiled the "Report on the Market Supply and Demand Pattern and Investment Prospects of China's Pharmaceutical Intermediates Industry from 2023 to 2028", which provides important references for investment decisions, strategic planning, and industry research of enterprises, scientific research, investment institutions, and other units.

Intermediates, an indispensable part of the pharmaceutical manufacturing chain, initially attracted a large number of small chemical enterprises due to low investment, high returns, and low entry barriers. Riding on the wave of explosive growth in the industry, the market size rapidly expanded.   In recent years, the country has attached great importance to the construction of the raw material and pharmaceutical intermediate industries. During the 13th Five Year Plan period, the country vigorously carried out the construction of centralized production bases for active pharmaceutical ingredients, and in the 14th Five Year Plan, encouraged enterprises to continuously strengthen their advantages in systematic manufacturing and create integrated development advantages of active pharmaceutical ingredients and preparations. China has focused on implementing industrial policies to support their long-term development.   Under this guidance, the pharmaceutical and chemical industry is steadily advancing towards standardized environmental protection and innovative development. Pharmaceutical manufacturing enterprises are accelerating the improvement of production processes, solving high energy consumption and pollution problems, and pursuing high-end pharmaceutical intermediates with stable and controllable quality, economic efficiency, and high product added value as the mainstream.   Overview of pharmaceutical intermediates Pharmaceutical intermediates are fine chemical products in the production process of pharmaceutical raw materials to active pharmaceutical ingredients or drugs, usually high-tech intensive and high value-added specialty chemicals.   Drug synthesis relies on high-quality pharmaceutical intermediates. According to the regulations of the China National Medical Products Administration, pharmaceutical intermediates can be regarded as raw materials for drugs and do not need to be produced and approved according to drug regulations or batch number applications.   However, due to its application in drug synthesis, the product quality needs to reach a certain level and usually needs to be reviewed by customers before becoming a qualified supplier.   According to their therapeutic fields, pharmaceutical intermediates can be divided into major categories such as antibiotic drug intermediates, antipyretic and analgesic drug intermediates, sedative and hypnotic drug intermediates, cardiovascular system drug intermediates, chemotherapy drug intermediates, etc; According to the drug structure, it can be divided into nucleotide intermediates, fluorine-containing intermediates, heterocyclic intermediates, and heavy metal ion containing intermediates.After more than 30 years of steady development, the chemical raw materials and intermediates required for pharmaceutical production in China have basically achieved matching, and only a small number of high-end intermediates with complex synthetic technologies need to be imported to meet them; Moreover, due to China's abundant resources and low raw material prices, many intermediates have been exported in large quantities.   In the era of the epidemic, the global pharmaceutical market has been affected by the rising demand for active pharmaceutical ingredients. As a linked industry, pharmaceutical intermediates have been stimulated to a certain extent, buffering the downward trend of production in China since 2016, and the market size has gradually recovered.   Data shows that in 2021, China's production of pharmaceutical intermediates reached 10.32 million tons, a year-on-year increase of 2.13%; The market size will reach 218.4 billion yuan and is expected to exceed 290 billion yuan by 2026. Excluding the objective factors of the epidemic, the core development of China's pharmaceutical intermediate market is influenced by multiple driving forces.   Currently, the deepening division of labor in the international industrial chain continues to shift the focus of the global pharmaceutical intermediate industry to the Asian region. With years of technological accumulation in the fields of medicine and fine chemicals, China has formed an intellectual property system with core market competitiveness. A large number of first-class R&D personnel and industrial workers are active on the production line, constantly improving the level of production technology while ensuring stable production operation.   Based on the principle of "strengthening strength and emphasizing innovation", China's position in the international supply chain has steadily improved.   On the other hand, the "patent cliff" is approaching one after another, and the development of China's pharmaceutical intermediate industry is also about to usher in a key opportunity: the urgently needed market space for generic drugs will increase the overall production and market size.   With the technological innovation of China's pharmaceutical industry, the field of innovative biopharmaceutical research and development is rapidly upgrading, and the demand for high-end intermediates is increasing. Although the added value and technological complexity of pharmaceutical intermediate products in China have significantly increased compared to the initial stage, their level of development is not yet sufficient to fully meet the rapidly expanding industrial demand, especially for some products with higher technological levels, and independent, stable, and high-quality production lines have not yet been fully established.   To meet the development goals of the industry, the pharmaceutical intermediate industry will continuously optimize its production processes, promote research and development work, and expand its product application fields, becoming a strong guarantee for its diversified development.   Looking at the overall social environment, the acceleration of population aging and the increasing demand for medical care are both opportunities and challenges. In order to protect people's health and improve their quality of life, as a necessary path for research and production, the pharmaceutical intermediate industry will also develop synchronously.

Pharmaceutical intermediate refers to intermediate compounds used in the pharmaceutical process to synthesize drugs. They are key intermediate products that are gradually synthesized into drugs through a series of organic synthesis reactions, starting from raw materials or natural products. Pharmaceutical intermediates play an important role in drug development and production. They are one of the key steps in converting molecules with therapeutic activity into final drugs. By controlling the synthesis route of intermediates and optimizing reaction conditions, efficient and sustainable drug production can be achieved.   There are many types of pharmaceutical intermediates, and the following are some common pharmaceutical intermediates:   Intermediate of benzene ring Benzene ring intermediates refer to intermediate products or molecules formed in chemical reactions that contain a benzene ring structure. The benzene ring is a cyclic structure formed by six carbon atoms, which has stability and special electronic properties. It is widely present in organic compounds and many natural products, and plays an important role in synthesizing new compounds, constructing organic frameworks, and adjusting molecular properties.   Here are some common benzene ring intermediates:   Phenol: Phenol is a compound containing a benzene ring and a hydroxyl group (- OH). It can be formed by replacing the hydrogen on the benzene ring with a hydroxyl group. Phenol and its derivatives have important applications in the pharmaceutical, dye, and chemical industries.   Aniline: Aniline is a compound containing a benzene ring and an amino group (- NH2). It can be formed by replacing the hydrogen on the benzene ring with an amino group. Aniline and its derivatives have a wide range of applications in the dye, pharmaceutical, and rubber industries. Pyridine intermediate Pyridine intermediates refer to intermediate products or molecules formed in chemical reactions that contain pyridine ring structures. Pyridine is a six membered heterocyclic ring composed of five carbon atoms and one nitrogen atom. It has stability and unique electronic properties, making these intermediates very valuable in constructing complex molecular skeletons, introducing specific functional groups, and regulating molecular properties, and can be applied in the fields of organic synthesis and drug development. Pyridine itself is also an important compound, commonly used as a solvent and a component of many drugs and natural products.   Here are some common pyridine intermediates:   Aminopyridine is an organic compound with a pyridine ring and an amino group. It is a derivative of pyridine, with an amino substituent on the pyridine ring in its structure. In drug research, aminopyridine and its derivatives play an important role. For example, 4-aminopyridine is used as a drug to treat multiple sclerosis and myasthenia gravis, which can improve muscle control and alleviate symptoms by increasing nerve conduction velocity.   Niacinamide: Niacinamide is a compound containing a pyridine ring and an amide group. It is a form of vitamin B3 widely used in the pharmaceutical and health product industries.   Pyridinecarboxylic acid: Pyridinecarboxylic acid is a type of compound containing a pyridine ring and a carbonyl (ketone or acid) group. It can be formed by replacing the hydrogen atom on pyridine with a carbonyl group. Pyrinone compounds are commonly used as intermediates in organic synthesis and drug development, and can undergo various chemical reactions.  

The efficiency and yield improvement of chemical and pharmaceutical intermediate synthesis can mainly be achieved from the following aspects:   1. Optimize reaction conditions: Appropriate reaction conditions are crucial for improving the efficiency and yield of intermediate synthesis. By adjusting parameters such as the ratio of reactants, temperature, and reaction time, higher reaction rates and higher product yields can be achieved. In addition, catalysts can also be considered to improve reaction efficiency. Catalysts can accelerate the reaction rate and reduce the activation energy of the reaction, thereby improving the efficiency and yield of intermediate synthesis.       2. Optimizing the reaction process: A reasonable reaction process also plays a crucial role in the efficiency and yield of intermediate synthesis. For example, continuous flow reactors can be used instead of traditional batch reactors to achieve higher yields through continuous feeding and continuous product collection. In addition, it is also possible to consider using stationary phase reactions or recovering reaction solvents for reuse to improve the efficiency and yield of intermediate synthesis.       3. Optimize the synthesis route: In the process of intermediate synthesis, choosing a suitable synthesis route is also very important. Some synthetic routes may generate a large amount of by-products, resulting in low product yields and additional processing and purification costs. Therefore, by optimizing the synthesis route and selecting methods that can directly generate target intermediates, the efficiency and yield of synthesis can be greatly improved.       4. Optimize catalyst design: Suitable catalysts also play an important role in improving the efficiency and yield of intermediate synthesis. By designing the physical and chemical properties of catalysts rationally, the reaction rate and selectivity can be improved. For example, using renewable catalysts or catalysts fixed on carriers can improve the utilization efficiency of catalysts, reduce catalyst losses, and increase synthesis efficiency and yield.       5. Optimize product separation and purification processes: In the intermediate synthesis process, product separation and purification are often key links that affect yield and purity. By optimizing the product separation and purification process, such as selecting appropriate solvents, adjusting temperature and pressure parameters, efficient separation and purification can be achieved, and yield and purity can be improved.       6. Optimize waste management and resource utilization: During the intermediate synthesis process, waste and by-products are generated. Reasonably handling these wastes and converting them into valuable resources is also a way to improve efficiency and yield. For example, catalyst recovery and regeneration technology can be used to reduce catalyst loss and waste emissions, achieve waste minimization and resource utilization.       7. Introducing intelligent and automated technology: By introducing intelligent and automated technology, real-time monitoring and control of the reaction process can be achieved, problems can be discovered and solved in a timely manner, and the controllability and consistency of the reaction can be improved, thereby enhancing the efficiency and yield of intermediate synthesis.       In summary, by optimizing reaction conditions, reaction processes, synthesis routes, catalyst design, and other aspects, combined with measures such as optimizing product separation and purification processes, waste treatment, and resource utilization, the efficiency and yield of chemical and pharmaceutical intermediate synthesis can be effectively improved.

Pharmaceutical intermediates are key raw materials in the pharmaceutical process, and their quality and stability have a significant impact on the quality of the final product. Therefore, storage conditions and precautions are crucial for ensuring the quality and stability of intermediates.       Firstly, regarding the storage conditions of pharmaceutical intermediates, the following points need to be noted:   1. Temperature: Most pharmaceutical intermediates are sensitive to temperature, so high and low temperature environments should be avoided. Generally speaking, the storage temperature of intermediates should be at room temperature, avoiding exposure to sunlight or freezing.   2. Humidity: Humidity is also an important factor for many pharmaceutical intermediates, as high or low humidity can cause changes in the intermediates. Therefore, appropriate humidity should be maintained as much as possible during storage.   3. Light exposure: Some pharmaceutical intermediates are also sensitive to light and are prone to loss of activity or reaction due to exposure to light. Therefore, a storage method that avoids light should be chosen to avoid direct exposure to strong light.   4. Packaging: In addition, for some special pharmaceutical intermediates, special packaging is required to protect their quality. For example, for oxygen sensitive intermediates, inert atmosphere packaging can be chosen to reduce the impact of oxygen.   In addition to storage conditions, precautions for pharmaceutical intermediates are also very important:   1. Label identification: When storing pharmaceutical intermediates, it should be ensured that each container has clear label identification, indicating the name, batch number, production date, and other information of the intermediate for traceability and management.   2. Regular inspection: Regularly check the storage environment and the status of intermediates to ensure that they meet the required storage conditions, and promptly handle any abnormal situations.   3. Prevent confusion: When storing, be careful to avoid mixing different intermediates to avoid confusion and misuse.   4. Safety: Some pharmaceutical intermediates may be toxic or harmful to the human body, so it is important to comply with relevant safety regulations and take protective measures during storage and operation.       Overall, the storage conditions and precautions for pharmaceutical intermediates are crucial for ensuring their quality and stability. Only by strictly storing and managing according to requirements can we ensure that the quality of intermediates is not affected, thereby guaranteeing the quality and safety of the final drug.
