Description

Ceftezole Sodium is a semi-synthetic, broad-spectrum cephalosporin antibiotic. This compound is valued for its potent antibacterial activity against a wide range of Gram-positive and some Gram-negative bacteria, making it a critical intermediate in pharmaceutical manufacturing. It is primarily utilized by the pharmaceutical industry for the synthesis of sterile injectable antibiotic formulations.

Application

• Pharmaceutical Active Ingredient (API): Primary use as the active pharmaceutical ingredient in injectable antibiotic preparations.
• Sterile Injectable Formulations: Manufacture of lyophilized (freeze-dried) powders or solutions for intravenous or intramuscular administration.
• Research & Development: Used as a reference standard or intermediate in antimicrobial research and new drug development projects.
• Veterinary Medicine: Formulation of antibiotic treatments for bacterial infections in animals.
