Description

Desfuroyl Ceftiofur Cysteine Disulfide is a key intermediate in the synthesis of the third-generation cephalosporin antibiotic, ceftiofur. This compound is critical for ensuring the purity and efficacy of the final active pharmaceutical ingredient (API) used in veterinary medicine. It is primarily required by manufacturers in the pharmaceutical and animal health industries for the production of high-quality antimicrobial treatments.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of Ceftiofur, a broad-spectrum veterinary antibiotic.
• Veterinary Drug Manufacturing: Used in the production of injectable and intramammary formulations for treating bacterial infections in livestock.
• API (Active Pharmaceutical Ingredient) Production: Serves as a high-purity precursor in GMP-compliant manufacturing processes for final drug substances.
• Research & Development: Utilized in analytical laboratories for method development, reference standards, and quality control testing of ceftiofur-based products.
• Metabolite Studies: Employed in pharmacokinetic and metabolic pathway research related to ceftiofur therapy in animals.
