Description

Cefoxitin is a second-generation cephamycin antibiotic derived from cephamycin C, belonging to the β-lactam class. Its primary value lies in its broad-spectrum bactericidal activity, particularly against anaerobic bacteria and β-lactamase-producing strains, making it a critical agent in combating serious infections. This compound is essential for the pharmaceutical industry, specifically in the formulation of injectable antibiotics for hospital use, and serves as a key reference standard in analytical and research laboratories. Cefoxitin CAS NO 56082-95-2 is a vital component in the global fight against resistant pathogens.

Application

• Pharmaceutical Active Ingredient (API): Primary use in the manufacture of sterile injectable antibiotic formulations for clinical use.
• Microbiological Research: Used as a reference standard and selective agent in studies of bacterial resistance, particularly for detecting methicillin-resistant *Staphylococcus aureus* (MRSA).
• Quality Control & Analytical Testing: Serves as a certified reference material (CRM) for HPLC, LC-MS, and other analytical methods in pharmaceutical QC labs.
• Veterinary Medicine: Employed in the development of antibacterial treatments for livestock and companion animals.
• Hospital Infection Control: Used in diagnostic kits and media for the identification of specific resistant bacterial strains in clinical settings.
