What are the production characteristics of pharmaceutical intermediates?

Looking at the entire industry, there are currently six characteristics in the production of pharmaceutical intermediates in my country: First, most of the production enterprises are private enterprises, with flexible operation and small investment scale, basically between several million and 20 million yuan; second, the geographical distribution of production enterprises is relatively concentrated

What is the difference between pharmaceutical intermediates and APIs?

As can be seen from the definition, the intermediate is the key product of the previous process of making the API, which is different in structure from the API. In addition, there are methods for testing APIs in the Pharmacopoeia, but there are no intermediates. When it comes to certification, currently FDA requires intermediates to be registered, COS does not, but the CTD file must have a detailed process description of the intermediate. In China, there is no GMP mandatory requirement for intermediates.

What are the classifications of APIs?

According to the source, it can be divided into chemically synthesized APIs and natural chemical APIs. (1) Chemical synthesis of APIs Chemically synthesized APIs can be further divided into inorganic synthetic APIs and organic synthetic APIs. Inorganic synthetic APIs are inorganic compounds, such as aluminum hydroxide used to treat stomach; organic synthetic APIs mainly refer to APIs (aspirin, caffeine, etc.) obtained from organic chemical raw materials through a series of organic chemical reactions.

What chemicals are in dye intermediates?

Dye intermediates mainly include benzene-based intermediates, toluene-based intermediates, naphthalene-based intermediates and anthraquinone-based intermediates. In addition, there are also some heterocyclic intermediates. The reaction processes commonly used in the production of intermediates mainly include nitration, sulfonation, halogenation, reduction, amination, hydrolysis, oxidation, condensation, etc. The synthesis of an intermediate with a complex structure often requires many unit processes, and sometimes different basic materials and different synthetic routes can be used.
