Description

Phosphomycin Calcium Salt is the calcium salt of the broad-spectrum antibiotic fosfomycin. This compound is valued for its role as a key intermediate in the synthesis of pharmaceutical-grade fosfomycin, ensuring high purity and reliable performance in downstream manufacturing. It is primarily required by manufacturers in the pharmaceutical and veterinary medicine industries for producing antibiotic formulations.

Application

• Pharmaceutical Intermediate: A critical starting material for the synthesis of fosfomycin tromethamine and other active pharmaceutical ingredients (APIs).
• Antibiotic Production: Used in the manufacturing of oral and injectable antibiotic formulations targeting a wide range of bacterial infections.
• Veterinary Medicine: Employed in the production of antimicrobial treatments for livestock and companion animals.
• Research & Development: Serves as a reference standard and building block in microbiological and pharmacological research.
• Chemical Synthesis: Acts as a precursor in organic synthesis for creating novel fosfomycin derivatives and analogs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
