Pharmaceutical intermediates are compounds used during the synthesis of active pharmaceutical ingredients (APIs). They are intermediate products in the chemical process that ultimately leads to the production of the final API. They can be used to make drugs for various therapeutic areas, including cancer, cardiovascular diseases, and central nervous system disorders. Pharmaceutical intermediates play a crucial role in determining the quality, purity, and stability of the final API, and therefore, their manufacturing and quality control are strictly regulated by government agencies. The proper selection and control of pharmaceutical intermediates is critical to ensuring the safety and efficacy of the final API.
