Concept

The so-called Pharmaceutical Intermediates are actually some chemical raw materials or chemical products used in the pharmaceutical synthesis process. This kind of chemical product does not require a production license for drugs, and can be produced in ordinary chemical plants. As long as it reaches some levels, it can be used for the synthesis of drugs.

Effect

Pharmaceutical production requires a lot of special chemicals. Most of these chemicals were originally produced by the pharmaceutical industry. However, with the deepening of social division of labor and the advancement of production technology, the pharmaceutical industry has transferred some pharmaceutical intermediates to chemical companies for production. Pharmaceutical intermediates are fine chemical products, and the production of pharmaceutical intermediates has become a major industry in the international chemical industry.
