Ceftiofur Free Acid is a core intermediate of third-generation cephalosporin antibiotics for veterinary use, serving as the parent compound for synthesizing ceftiofur sodium, ceftiofur hydrochloride and other soluble salt forms. It features high purity, stable quality and strong antibacterial activity potential, and is widely used in the production of veterinary antibacterial preparations.

Core Properties & Mechanism: As an amphoteric compound, it contains carboxyl and amino groups, which are easy to decompose under strong acid and alkali conditions, so it needs strict storage control. Its derivative salt forms exert bactericidal effects by binding to bacterial penicillin-binding proteins (PBPs) and inhibiting bacterial cell wall synthesis. The antibacterial spectrum of its derivatives covers major pathogenic bacteria in animal husbandry: - Gram-negative bacteria: *Actinobacillus pleuropneumoniae* (swine pleuropneumonia), *Haemophilus parasuis* (swine Glässer's disease), *Pasteurella multocida* (bovine pasteurellosis); - Gram-positive bacteria: *Streptococcus suis* (swine streptococcosis), *Staphylococcus aureus* (bovine mastitis); - Other pathogens: *Escherichia coli* (poultry colibacillosis), *Riemerella anatipestifer* (duck serositis).

Main Application Scenarios: 1. Pharmaceutical synthesis: Used as raw material to produce ceftiofur sodium, ceftiofur hydrochloride and other soluble preparations, adapting to injection, water-soluble powder and other dosage forms; 2. Veterinary preparation R&D: Applied in the development of new ceftiofur derivatives and long-acting preparations, improving drug efficacy and stability; 3. Intensive breeding supporting: Its synthesized salt forms are widely used in swine, cattle, poultry and other breeding industries to prevent and treat bacterial infections.

Product Advantages: 1. High purity foundation: Industrial grade purity ≥98.0%, refined grade ≥99.0%, low impurity content, providing high-quality raw material for salt synthesis; 2. Strong derivatization adaptability: Stable chemical properties under standard storage conditions, easy to react with sodium, hydrochloric acid and other substances to form soluble salts; 3. Strict quality control: Produced in GMP-certified workshops, each batch undergoes HPLC purity detection, moisture determination and impurity analysis, with full-process traceability; 4. Complete supporting documents: Provide COA, MSDS, TDS and other full-set technical documents for each batch, meeting international import and export compliance requirements; 5. Flexible supply: Support conventional packaging and customized specifications, adapting to industrial production and R&D needs.

Storage requirements: Seal and store in a cool, dry and well-ventilated warehouse, temperature ≤25℃, relative humidity ≤65%; avoid sunlight, rain, fire and oxidants; shelf life is 24 months when unopened and stored properly.
