Description

Disodium Phosphonomycin is the disodium salt form of fosfomycin, a broad-spectrum antibiotic. This compound is valued for its role as a key pharmaceutical intermediate in the synthesis of active pharmaceutical ingredients (APIs) and as a reference standard for analytical purposes. It is primarily utilized by manufacturers and research institutions in the pharmaceutical, biotechnology, and analytical chemistry sectors.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of fosfomycin-based antibiotic APIs.
• Analytical Reference Standard: Used for quality control, method validation, and calibration in HPLC, LC-MS, and other analytical techniques.
• Biochemical Research: Employed in microbiological studies to investigate bacterial cell wall synthesis and antibiotic resistance mechanisms.
• Veterinary Medicine: A component in the development of antimicrobial treatments for animal health.
• Active Pharmaceutical Ingredient (API) Manufacturing: Serves as a direct precursor in the production of finished dosage forms.

Quality Control

Our Disodium Phosphonomycin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements for pharmaceutical intermediates and reference standards. A Certificate of Analysis (COA) detailing specific results for assay, impurities, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
