Description

Ceftizoxime is a semi-synthetic, broad-spectrum third-generation cephalosporin antibiotic. It is valued for its potent activity against a wide range of Gram-positive and Gram-negative bacteria, including many β-lactamase-producing strains. This makes it a critical active pharmaceutical ingredient (API) for the formulation of injectable antibiotics. Pharmaceutical manufacturers and research institutions globally rely on high-purity Ceftizoxime CAS NO 68403-31-6 for developing effective therapeutic solutions.

Application

• Pharmaceutical API: Primary use as the active ingredient in sterile injectable formulations for hospital use.
• Antibiotic Drug Manufacturing: Synthesis of finished dosage forms, including vials and intravenous solutions, for treating severe infections.
• Research & Development: Used in microbiological studies, mechanism of action research, and development of new combination therapies.
• Veterinary Medicine: Formulation of antibiotics for treating bacterial infections in animals.
• Reference Standard: Serves as a high-purity chemical standard for quality control and analytical testing in laboratories.
