In the past 20 years, the world’s pharmaceutical industry has made unprecedented progress. At the end of the 1990s, the world drug market reached 265 billion US dollars, of which antibacterial drugs accounted for a considerable proportion.
Pharmaceutical intermediates can be divided into antibiotic drug intermediates, antipyretic and analgesic pharmaceutical intermediates, cardiovascular system pharmaceutical intermediates, and anti-cancer pharmaceutical intermediates. There are many types of specific pharmaceutical intermediate products, such as imidazole, furan, phenolic intermediates, aromatic intermediates, pyrrole, pyridine, biochemical reagents, sulfur-containing, nitrogen-containing, halogen compounds, heterocyclic compounds, starch, mannitol , Microcrystalline cellulose, lactose, dextrin, glycols, powdered sugar, inorganic salts, ethanol intermediates, stearates, amino acids, ethanolamines, potassium salts, sodium salts and other intermediates, etc. Wait.
Chemical and pharmaceutical intermediates: As the name implies, in the process of drug synthesis, the raw materials and target compounds are removed, and the rest is the intermediate. Various pharmaceutical and chemical intermediates are also produced when synthesizing a wide variety of drugs. Although these intermediates are different from the target compounds, their functions can often be used by people. Briefly introduce several common pharmaceutical and chemical intermediates.
Pharmaceutical intermediates are fine chemical products in the production process from pharmaceutical chemical raw materials to raw materials or drugs. The synthesis of chemical drugs depends on high-quality pharmaceutical intermediates. This kind of chemical product does not require a pharmaceutical production license and can be produced in an ordinary chemical plant. As long as it reaches a certain level, it can be used for pharmaceutical synthesis. Our country needs more than 2,000 kinds of raw materials and intermediates for chemical industry every year. After years of development, the chemical raw materials and intermediates required for pharmaceutical production in our country can basically be matched, and only a small part needs to be imported. Moreover, due to my country’s abundant resources and low raw material prices, many intermediates have been exported in large quantities.
