Description

Cefquinome is a fourth-generation cephalosporin antibiotic belonging to the β-lactam class, specifically developed for veterinary use. Its primary value lies in its broad-spectrum activity against Gram-positive and Gram-negative bacteria, including many resistant strains, making it a critical tool in modern veterinary medicine. This product is essential for manufacturers in the animal health pharmaceutical industry, formulators of veterinary injectables, and research institutions developing new antimicrobial therapies. Cefquinome CAS NO 84957-30-2 is supplied as a high-purity active pharmaceutical ingredient (API) to ensure efficacy and safety in final medicinal products.

Application

Cefquinome is a potent veterinary antibiotic with specific applications in treating bacterial infections in livestock and companion animals.

• Veterinary Pharmaceutical Manufacturing: As an active pharmaceutical ingredient (API) in injectable formulations for the treatment of respiratory, mammary, and systemic infections.
• Mastitis Treatment in Dairy Cattle: A key therapeutic for clinical mastitis caused by susceptible pathogens like E. coli and Staphylococcus aureus.
• Porcine Respiratory Disease Complex (PRDC): Used to combat bacterial components of respiratory diseases in swine.
• Companion Animal Medicine: Treatment of skin, soft tissue, and urinary tract infections in dogs and cats.
• Poultry Health: Management of bacterial infections such as collibacillosis in poultry flocks.
• Research & Development: Used as a reference standard in microbiological assays and for developing new combination therapies.

Quality Control

Our Cefquinome is manufactured under strict quality management systems to ensure it meets the stringent requirements for veterinary pharmaceutical ingredients. Each batch is tested against comprehensive specifications, including identity, purity, and impurity profiles, utilizing advanced analytical techniques like HPLC. Certificates of Analysis (COA) are provided with every shipment, detailing all test results. We adhere to relevant Good Manufacturing Practice (GMP) principles for active substances intended for veterinary medicinal products.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
