Product Application of Thiotriazolin CAS#357172-63-5
This substance serves as a versatile intermediate for chemical processing and drug-related manufacture to produce multiple biologically-active molecules. As verified by chemical-directory records, its molecular framework corresponds to two well-known pharmaceutical reference impurities, namely Cefaclor Impurity 67 and Acetylcysteine Impurity 115. For that reason, it is widely supplied as a certified-reference standard for laboratory detection and finished-drug quality-control testing.
