Description

Cefquinome Sulfate CAS NO 123766-80-3 is a fourth-generation cephalosporin antibiotic belonging to the aminothiazolyl class, specifically developed for veterinary medicine. Its primary value lies in its broad-spectrum activity against Gram-positive and Gram-negative bacteria, including many β-lactamase-producing strains. This makes it a critical active pharmaceutical ingredient (API) for manufacturers developing injectable solutions to treat respiratory, mastitis, and other serious bacterial infections in livestock, primarily cattle and swine.

Application

• Veterinary Pharmaceutical API: Primary use as the active ingredient in injectable antibiotic formulations for food-producing animals.
• Bovine Respiratory Disease (BRD) Treatment: Formulated for the treatment of respiratory infections in cattle caused by susceptible pathogens like Pasteurella spp. and Mannheimia haemolytica.
• Clinical Mastitis Treatment in Cattle: Used in intramammary infusions for the treatment of acute mastitis in lactating cows.
• Swine Respiratory Disease Treatment: Effective against infections caused by organisms such as Actinobacillus pleuropneumoniae and Pasteurella multocida.
• Metritis and Other Bacterial Infections: Applied in the treatment of postpartum uterine infections (metritis) and other systemic bacterial diseases in livestock.
• Veterinary Generic Drug Manufacturing: Sourced by generic veterinary drug manufacturers for producing cost-effective therapeutic equivalents.

Quality Control

Our Cefquinome Sulfate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for veterinary pharmaceutical applications. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming specifications for identity, potency, purity, and related substances via validated methods such as HPLC. We support compliance with relevant veterinary pharmacopoeial standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). The product is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent degradation. Keep away from incompatible materials.
