Description

Cefquinome Sulfate is a fourth-generation cephalosporin antibiotic belonging to the veterinary pharmaceutical class. This compound is valued for its broad-spectrum activity against Gram-positive and Gram-negative bacteria, including strains resistant to earlier-generation antibiotics. It is primarily utilized in the animal health industry for the treatment of respiratory and other systemic infections in livestock, ensuring animal welfare and productivity. Cefquinome Sulfate CAS NO 118443-89-3 represents a critical tool in modern veterinary medicine for combating bacterial diseases.

Application

• Veterinary Pharmaceutical Formulations: Primary active pharmaceutical ingredient (API) in injectable solutions for the treatment of bacterial infections in cattle, swine, and horses.
• Treatment of Bovine Respiratory Disease (BRD): Effective against key pathogens like Pasteurella multocida and Mannheimia haemolytica.
• Swine Respiratory Disease Control: Used for managing infections caused by Actinobacillus pleuropneumoniae and other respiratory pathogens.
• Mastitis Treatment in Dairy Cattle: Applied for intramammary infusions to combat udder infections.
• Metritis and Other Systemic Infections: Addresses postpartum uterine infections and septicemia in various livestock species.
• Veterinary Generic Drug Manufacturing: Sourced by pharmaceutical companies for the production of generic veterinary medicinal products.
• Research & Development: Used in microbiological studies and the development of new antibacterial therapies.
