Pharmaceutical 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. Drug intermediates are hygienically formulated using high grade raw materials and they are used in the pharmaceutical and cosmetic industry.
