azithromycin and its Impurities
A broad spectrum antibiotic which is used to inhibit some Gram-positive bacteria, some Gram-negative bacteria, and many atypical bacteria. Azithromycin is an azalide which is a type of macrolide antibiotic. It prevents bacteria from growing by interfering in its protein synthesis. Reference standards of Azithromycin API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
