According to their application fields, pharmaceutical intermediates can be classified into major categories such as antibiotic intermediates, antipyretic and analgesic pharmaceutical intermediates, cardiovascular system pharmaceutical intermediates, and anti-cancer pharmaceutical intermediates. The specific types of pharmaceutical intermediate products include imidazole, furan, phenolic intermediates, aromatic intermediates, pyrrole, pyridine, biochemical reagents, sulfur-containing compounds, ammonia containing compounds, halogen compounds, heterocyclic compounds, etc.
According to the classification of technical content, pharmaceutical intermediates can be divided into primary intermediates and advanced intermediates. Primary intermediate suppliers can only provide simple intermediate production and are at the forefront of the industry chain, facing significant competitive and price pressures; Advanced intermediate suppliers can provide advanced intermediate production with high technological content, maintain close ties with multinational companies, and have high profit margins and bargaining power.
According to structural characteristics, pharmaceutical intermediates can be classified into nucleotide intermediates, fluorine-containing intermediates, heterocyclic intermediates, and heavy metal ion containing intermediates. Nucleotide intermediates refer to compounds with nucleotides as the basic structural unit, mainly used for synthesizing antiviral and anti-tumor drugs; Fluorinated intermediates refer to compounds containing fluorine atoms in their molecular structure, mainly used for the synthesis of antibiotics and anticancer drugs; Heterocyclic intermediates refer to compounds containing rings composed of non carbon atoms in the molecular structure, which are mainly used to synthesize drugs against gastric ulcer and breast cancer; Intermediates containing heavy metal ions refer to compounds with heavy metal ions (such as platinum, rhodium, etc.) in their molecular structure, mainly used for the synthesis of anti-tumor drugs.
The above are some common classification methods and representative products of pharmaceutical intermediates.
