aztreonam and its Impurities
Aztreonam is a monocyclic beta-lactam antibiotic originally isolated from Chromobacterium violaceum. It is resistant to beta-lactamases and is used in gram-negative infections, especially of the meninges, bladder, and kidneys. Reference standards of Aztreonam API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
