Description

Aztreonam CAS NO 149496-40-2 is a synthetic monobactam antibiotic belonging to the β-lactam class. It is valued for its potent and specific bactericidal activity against aerobic Gram-negative bacteria, including Pseudomonas aeruginosa. This product is essential for pharmaceutical manufacturers and research institutions developing injectable antibiotic formulations and novel antimicrobial agents. Its stability profile makes it a critical component in combating serious infections where other β-lactams may be ineffective.

Application

• Pharmaceutical Active Ingredient (API): Primary use in the manufacture of sterile injectable antibiotic formulations for hospital use.
• Research & Development: Serves as a key reference standard and building block in microbiological research and the development of new combination therapies.
• Veterinary Medicine: Used in the development of treatments for bacterial infections in animals.
• Microbiological Media: Incorporated into selective culture media for laboratory identification of specific bacterial strains.

Quality Control

Our Aztreonam is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption.
