Description

Cefsulodin CAS NO 62587-73-9 is a semi-synthetic, β-lactamase-resistant cephalosporin antibiotic. It is valued for its potent and specific activity against Pseudomonas aeruginosa, making it a critical tool in microbiological research and quality control. This compound is essential for pharmaceutical R&D laboratories, clinical diagnostics, and manufacturers of culture media and antibiotic susceptibility testing products.

Application

• Microbiological Research & Assay Development: Used as a selective agent in studies targeting Pseudomonas aeruginosa and other Gram-negative bacteria.
• Clinical Diagnostics: A key component in antibiotic susceptibility test (AST) discs, strips, and panels for determining bacterial resistance profiles.
• Culture Media Preparation: Incorporated into selective and differential agar media for the isolation and identification of specific bacterial pathogens in environmental and clinical samples.
• Pharmaceutical Reference Standard: Serves as a high-purity chemical reference material (CRM) for quality control and analytical method validation in antibiotic production.
• Veterinary Microbiology: Applied in diagnostic kits and media for bacterial infection testing in animals.
• Academic & Institutional Laboratories: Utilized in university and research institute labs for fundamental bacteriology and antibiotic mechanism studies.
