Description

Cefpiramide Sodium CAS NO 74849-93-7 is a semi-synthetic, broad-spectrum cephalosporin antibiotic belonging to the third generation. It is valued for its enhanced stability against β-lactamases and potent activity against a wide range of Gram-positive and Gram-negative bacteria. This high-purity active pharmaceutical ingredient (API) is essential for pharmaceutical manufacturers developing injectable antibiotic formulations for serious systemic infections.

Application

• Pharmaceutical API: Primary use as the active ingredient in sterile injectable antibiotic products.
• Hospital Infection Treatment: Formulated for treating severe infections such as septicemia, pneumonia, and complicated urinary tract infections.
• Bacterial Resistance Management: Used in clinical settings where infections are suspected or confirmed to be resistant to earlier-generation cephalosporins or penicillins.
• Research & Development: Serves as a reference standard and key intermediate in antimicrobial research and new drug development projects.
• Veterinary Medicine: Potential application in developing treatments for bacterial infections in animals.
