chemical supply plan
The raw materials for chemical supply are mainly divided into two categories: organic chemical raw materials and inorganic chemical raw materials. These are the basic substances of the pharmaceutical industry and are widely used in the synthesis of various active pharmaceutical ingredients (APIs) and intermediates.
Specifically, let's take a look:
Organic chemical raw materials
This is the most essential source of raw materials in the production of chemical drugs, mainly including:
Hydrocarbons and their derivatives, such as ethylene, benzene, toluene, xylene (PX), olefins, alkynes, etc., are the basis for synthesizing aromatic compounds and heterocyclic drugs.
Oxygenated organic compounds, such as methanol, ethanol, acetone, formaldehyde, acetic acid, esters, ketones, alcohols, aldehydes, etc., are often used as solvents or reaction intermediates.
Nitrogen containing organic compounds, such as amines, nitriles, amides, heterocyclic compounds, etc., are widely used in the synthesis of antibiotics, anti-tumor drugs, neurological drugs, etc.
Inorganic chemical raw materials
Mainly used to provide inorganic elements required for reactions or as auxiliary materials such as catalysts and precipitants:
Acid alkali salts: such as sulfuric acid, hydrochloric acid, nitric acid, caustic soda (sodium hydroxide), soda ash (sodium carbonate), sodium chloride, etc., used to adjust pH, neutralize reactions, or prepare inorganic salt drugs.
Elemental substances and gases, such as chlorine, oxygen, hydrogen, nitrogen, sulfur, etc., participate in key reactions such as oxidation, reduction, and chlorination.
Metallic minerals: minerals containing sodium, potassium, calcium, phosphorus, and magnesium, used for the preparation of electrolyte drugs or as catalyst carriers.
Starting materials and intermediates
Starting materials: including natural resources such as air, water, coal, oil, and natural gas, they are the starting point of the entire chemical chain.
Pharmaceutical intermediates such as vinyl chloride, acetone, methanol, 7-ACA (a key intermediate for cephalosporin antibiotics), although not the final drug, are crucial for synthesizing complex drugs.
It is worth mentioning that 99% of modern pharmaceutical production processes rely on oil and natural gas as source materials. From aspirin to the anti-cancer drug paclitaxel, the solvents, catalysts, and intermediates required for their synthesis mostly come from petrochemical products. For example, the crystallization of vitamin C, extraction of penicillin, and synthesis of tinib targeted drugs all rely on petrochemical materials such as benzene, methanol, and ethylene.
In addition, China holds a crucial position in the global supply of pharmaceutical raw materials, with the United States relying on imports of approximately 87% of medical chemical raw materials from China, covering multiple fields such as antibiotics, anticancer drugs, immunosuppressants, and more. In 2024, China produced about 42% of the world's major chemical products, becoming the world's largest producer and consumer of petrochemical products.
