Description

Phosphomycin Sodium CAS NO 103923-27-9 is the sodium salt form of the broad-spectrum antibiotic fosfomycin. This compound is valued for its unique mechanism of action, inhibiting bacterial cell wall synthesis at an early stage, which makes it effective against a range of Gram-positive and Gram-negative bacteria. It is a critical active pharmaceutical ingredient (API) primarily utilized in the pharmaceutical industry for the formulation of injectable antibiotic preparations.

Application

• Pharmaceutical API: Primary use as the active ingredient in sterile injectable formulations for systemic antibiotic therapy.
• Treatment of Severe Infections: Used in hospitals for combating complicated urinary tract infections (cUTIs), nosocomial infections, and infections caused by multidrug-resistant organisms.
• Combination Therapy: Employed in synergistic antibiotic combinations to enhance efficacy and overcome bacterial resistance mechanisms.
• Veterinary Medicine: Application in veterinary pharmaceuticals for treating bacterial infections in livestock and companion animals.
• Research & Development: Serves as a reference standard and key intermediate in microbiological research and the development of new antimicrobial agents.

Quality Control

Our Phosphomycin Sodium 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) detailing identity, purity, and impurity profiles are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under controlled humidity conditions. Recommended long-term storage temperature is between 2°C and 8°C.
