Definition of pharmaceutical intermediates

 

Pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of drug synthesis. This kind of chemical products can be produced in ordinary chemical plants without a production license for medicines, and when reaching a certain level, they can be used for the synthesis of medicines.

 

Types of pharmaceutical intermediates

At present, the most promising varieties of pharmaceutical intermediates are mainly as follows: nucleoside intermediates, cardiovascular intermediates, fluorine-containing intermediates and heterocyclic intermediates.

 

The important position of pharmaceutical intermediates

Pharmaceutical intermediates are an important link in the industrial chain of the pharmaceutical industry. The upstream are basic chemical raw materials, most of which are petrochemical products, such as acetylene, ethylene, propylene, butene and butadiene, toluene and xylene. The midstream belongs to the pharmaceutical fine chemical industry. Manufacturers of pharmaceutical intermediates synthesize crude intermediates or crude APIs, and sell the products to pharmaceutical companies in the form of chemical products, which are refined and then sold as drugs. The downstream is mainly the raw material medicine production industry, and the raw material medicine and the preparation are in the relationship between the upstream and downstream industrial chain. Therefore, the consumption demand of downstream pharmaceutical preparations will directly affect the demand for APIs, and then the demand for intermediates.
