Such substances have pharmacological or other direct effects in the diagnosis, treatment, remission, treatment or prevention of diseases, or can affect the function and structure of the body. Among them, the basic pharmaceutical raw materials are mainly composed of some molecules with a few functional groups. The basic chemical chemicals are used as raw materials. The production steps are only one or two simple steps, usually involving the production of derivatives. There are many terminal applications in this category, and the pharmaceutical industry is just one of them. It is also commonly used as a basic raw material for the synthesis of more elaborate molecular structures.
