Description

Pirlimycin is a lincosamide antibiotic specifically developed for veterinary use, with the CAS registry number 79548-73-5. This compound is valued for its targeted efficacy against Gram-positive bacteria, including strains resistant to other antibiotic classes. It is a critical active pharmaceutical ingredient (API) for manufacturers developing intramammary infusions and other therapeutic formulations for the global animal health industry, addressing mastitis and other bacterial infections in livestock.

Application

Pirlimycin is primarily utilized in veterinary pharmaceuticals. Its key applications include:

• Veterinary Antibiotic API: As the active ingredient in intramammary infusions for the treatment of bovine mastitis, particularly during the dry period.
• Livestock Health Management: Formulated into products for treating infections caused by susceptible Gram-positive pathogens in dairy cattle.
• Pharmaceutical R&D: Used in research and development of new antibiotic formulations and combination therapies for veterinary medicine.
• Generic Drug Manufacturing: Sourced by manufacturers producing generic versions of approved pirlimycin-based veterinary drugs.
