Pharmaceutical Intermediates

Pharmaceutical Intermediates are intermediate compounds produced during the production of active drugs, including 3-Amino-5-mercapto-1,2,4-triazole and 3-Amino-1,2,4-Triazole.Pharmaceutical Intermediates are key chemical raw materials in the drug synthesis process, between basic chemical raw materials and APIs. They are the "building blocks" of drug molecular structures, which are ultimately transformed into active pharmaceutical ingredients with therapeutic effects through a series of chemical reactions. The quality of Pharmaceutical Intermediates directly affects the safety, efficacy and stability of the final drug, so they have extremely high requirements for purity, impurity control and process stability.
