Description

Pefloxacin Mesylate CAS NO 70458-95-6 is the mesylate salt form of pefloxacin, a second-generation fluoroquinolone antibiotic. This compound is valued for its enhanced solubility and stability, making it a critical intermediate in pharmaceutical manufacturing. It is primarily required by active pharmaceutical ingredient (API) producers and research institutions developing antibacterial formulations.

Application

• Pharmaceutical Intermediate: Key starting material or intermediate in the synthesis of pefloxacin-based antibiotic APIs.
• Antibacterial Drug Formulation: Used in the research and development of finished dosage forms, including tablets and injectables.
• Microbiological Research: Serves as a reference standard in studies investigating fluoroquinolone activity and resistance mechanisms.
• Veterinary Medicine: Potential application in the development of antibacterial treatments for veterinary use.
• Analytical Standard: Used as a high-purity standard in quality control laboratories for HPLC, LC-MS, or other analytical methods.
