Description

Pefloxacinmesylate CAS NO 70458-45-6 is the mesylate salt form of pefloxacin, a second-generation fluoroquinolone antibiotic. This compound is valued for its enhanced solubility and stability compared to the free base, making it a critical intermediate in pharmaceutical manufacturing. It is primarily required by manufacturers of active pharmaceutical ingredients (APIs) for the production of antibacterial formulations.

Application

• Pharmaceutical Intermediate: Key raw material for synthesizing pefloxacin-based antibacterial APIs.
• Veterinary Medicine Production: Used in the development of antibacterial treatments for veterinary use.
• Research & Development: Serves as a reference standard and building block in antimicrobial research and new drug discovery.
• Formulation Studies: Utilized in pre-formulation and formulation development due to its favorable salt properties.
