Description

Cefapirin Sodium is a semi-synthetic, first-generation cephalosporin antibiotic in its sodium salt form. This compound is valued for its broad-spectrum bactericidal activity against a range of Gram-positive and some Gram-negative organisms. It is primarily utilized in the pharmaceutical industry for the formulation of injectable antibiotic preparations. Cefapirin Sodium CAS NO 54600-91-8 is a critical active pharmaceutical ingredient (API) for manufacturing sterile injectable solutions.

Application

• Pharmaceutical API: Primary use as the active ingredient in sterile injectable antibiotic formulations.
• Veterinary Medicine: Used in the development of treatments for bacterial infections in animals, particularly mastitis in dairy cattle.
• Research & Development: Serves as a reference standard and key intermediate in microbiological and pharmacological research.
• Hospital Formulations: Employed in hospital pharmacy settings for the preparation of specific antibiotic therapies.
• Bulk Drug Manufacturing: Supplied to pharmaceutical companies for large-scale production of finished dosage forms.
