Description

Cefoxitin is a second-generation, broad-spectrum cephamycin antibiotic derived from cephamycin C. This semi-synthetic compound is valued for its stability against β-lactamase enzymes, making it a critical agent in combating resistant bacterial strains. It is primarily utilized in the pharmaceutical industry for the formulation of injectable antibiotics, serving hospitals, clinical research, and API manufacturing sectors globally. Cefoxitin CAS NO 35607-66-0 is essential for developing treatments for serious abdominal, gynecological, and other infections.

Application

• Pharmaceutical Active Ingredient (API): Core component in the manufacture of injectable antibiotic formulations.
• Clinical & Hospital Use: Used in prepared solutions for the treatment of severe infections caused by susceptible anaerobic and aerobic bacteria.
• Microbiological Research: Serves as a standard or reagent in studies of bacterial resistance mechanisms and antibiotic efficacy.
• Veterinary Medicine: Employed in antibiotic preparations for treating bacterial infections in animals.
• Reference Standard: Used in quality control laboratories as a certified reference material for HPLC and other analytical methods.
• Antibiotic Susceptibility Testing: A key agent in diagnostic kits and panels for determining bacterial sensitivity in clinical microbiology.
