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

　　effect

　　Pharmaceutical production requires a large amount 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 improvement of production technology, the pharmaceutical industry has transferred some pharmaceutical intermediates to chemical enterprises for production. Pharmaceutical intermediates are fine chemical products, and the production of pharmaceutical intermediates has become a major industry in the international chemical industry.
