Description

Floxacillinsodium CAS NO 34214-51-2 is the sodium salt of flucloxacillin, a semi-synthetic penicillinase-resistant penicillin antibiotic. This compound is critical for formulating stable, injectable antibiotic preparations that target β-lactamase-producing staphylococci. It is primarily required by pharmaceutical manufacturers for producing sterile injectable solutions and by research institutions developing advanced antibacterial therapies.

Application

• Pharmaceutical Active Ingredient (API): Core component in the manufacture of sterile injectable antibiotic formulations.
• Hospital & Clinical Use: Used in ready-to-use injectable solutions for treating bacterial infections resistant to standard penicillins.
• Veterinary Medicine: Formulated for treating bacterial infections in livestock and companion animals.
• Research & Development: Serves as a reference standard and key intermediate in microbiological and pharmacological research.
• Bulk Drug Manufacturing: Supplied to compounding pharmacies and generic drug manufacturers for final dosage form production.
