Description

Bacitracin CAS NO 55852-84-1 is a complex polypeptide antibiotic mixture, primarily composed of Bacitracin A. It is valued for its potent bactericidal activity against a wide spectrum of Gram-positive organisms. This makes it a critical active pharmaceutical ingredient (API) for manufacturers in the pharmaceutical and veterinary medicine industries, particularly for topical formulations and animal feed additives.

Application

• Pharmaceutical API: Core ingredient in topical antibiotic ointments, creams, and powders for human use.
• Veterinary Medicine: Used in wound sprays, udder creams, and ophthalmic preparations for livestock and companion animals.
• Animal Nutrition: Incorporated into feed as a growth promoter and for the prevention of certain bacterial infections in poultry and swine.
• Microbiological Research: Serves as a selective agent in culture media for laboratory studies.
• Combination Therapies: Often formulated with other antibiotics like Neomycin and Polymyxin B for broad-spectrum coverage.

Quality Control

Our Bacitracin is produced and tested to meet stringent pharmacopeial standards. Each batch undergoes comprehensive analysis including identification, potency (assay), and impurity profiling to ensure compliance with USP, EP, and BP monographs. A detailed Certificate of Analysis (COA) documenting purity, microbiological quality, and heavy metal limits is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and potency.
