Description

Fosfomycin is a broad-spectrum, bactericidal antibiotic that inhibits bacterial cell wall synthesis by targeting the enzyme MurA. This unique mechanism of action makes it a valuable tool in combating multidrug-resistant bacterial infections. It is essential for the pharmaceutical industry, particularly in the formulation of antibiotics for human and veterinary medicine. Global procurement teams rely on consistent, high-purity Fosfomycin CAS NO 45629-00-3 for the development of effective therapeutic solutions.

Application

• Pharmaceutical Active Ingredient (API): Primary use in the manufacture of oral and injectable antibiotic formulations for human use.
• Veterinary Medicine: Used in treatments for bacterial infections in livestock and companion animals.
• Research & Development: Serves as a critical reference standard and intermediate in microbiological and pharmacological research.
• Combination Therapies: Employed in synergistic antibiotic combinations to enhance efficacy and overcome resistance.
• Urinary Tract Infection (UTI) Treatments: A key component in specific medications designed to treat uncomplicated UTIs.
