Description

Ceftizoxime is a third-generation, broad-spectrum 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 intermediate and active pharmaceutical ingredient (API) for manufacturers in the pharmaceutical industry, particularly for injectable antibiotic formulations. Ceftizoxime CAS NO 929101-91-7 is essential for producing effective treatments for serious infections.

Application

• Pharmaceutical API: Primary use as the active ingredient in sterile injectable antibiotic formulations.
• Hospital Infection Treatment: Used in drugs targeting severe infections such as pneumonia, septicemia, and complicated urinary tract infections.
• Surgical Prophylaxis: A key component in antibiotics administered to prevent post-operative infections.
• Research & Development: Serves as a reference standard and building block in antimicrobial research and new drug development.
• Veterinary Medicine: Employed in advanced antibiotic treatments for bacterial infections in animals.

Quality Control

Our Ceftizoxime is manufactured under strict quality management systems. It undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical use, with specifications aligning with major pharmacopoeial guidelines. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every batch to ensure full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed in a low-humidity environment to prevent moisture absorption. Recommended long-term storage temperature is 2-8°C.
