Bulk drug intermediates are the drugs used as raw materials for the production of bulk drugs, or they can refer to a material produced during synthesis of an API that must undergo further molecular change or processing before it becomes an API.

More Information

Intermediates are unavoidable products of chemical reactions and are widely used in pharmaceuticals, materials, chemicals, and other industries.

In the pharmaceutical industry, an active pharmaceutical ingredient (API) is a product of a synthesis process that has been completed and is used in the manufacture of bulk drugs and intermediates are some chemical raw materials or chemical products used in the synthesis process of APIs.

The application industries of pharmaceutical intermediates mainly include antibiotics, anticancer drugs, cardiovascular drugs, neurological drugs, hormone drugs, and immunosuppression.

Functions of intermediates

Intermediates serve a variety of responsibilities in the drug production process.

● They can serve as a link between the API and the finished medicine. The drug production process can be broken down into multiple steps using intermediates, each requiring a different chemical.

● They can modify reaction conditions and synthesis pathways, increasing drug synthesis efficiency and yields.

● They can be employed to modify the purification, crystallization, and solid characteristics of medicines.
