  • Applications

    Bacitracin Zinc (CAS 1405-89-6) is used in pharmaceutical contexts in topical antibiotic formulations (creams, ointments) and in ophthalmic preparations as antimicrobial agents. In agriculture and veterinary medicine, it is used as a feed additive for poultry and other livestock to support growth performance and disease control, and it appears in some veterinary topical products. In laboratory and research settings, bacitracin zinc serves as a selective antimicrobial agent in culture media and in antibiotic susceptibility testing. It may also be evaluated for limited cosmetic applications as an antimicrobial active ingredient in certain formulations.
