Description

Fleroxacinlactate CAS NO 896139-71-2 is the lactate salt form of fleroxacin, a synthetic broad-spectrum fluoroquinolone antibiotic. This formulation is critical for enhancing the solubility and bioavailability of the active pharmaceutical ingredient, which directly impacts the efficacy and stability of final drug products. It is an essential intermediate and active ingredient for pharmaceutical manufacturers developing antibacterial treatments targeting respiratory, urinary tract, and skin infections.

Application

• Pharmaceutical Active Ingredient (API): Primary use as the active component in the formulation of antibacterial injectables and oral dosage forms.
• Veterinary Medicine: Used in the development of antibacterial treatments for livestock and companion animals.
• Research & Development: Serves as a key reference standard and building block in microbiological and pharmacological research for novel antibiotic discovery.
• Intermediate Synthesis: Acts as a crucial precursor in the multi-step synthesis of more complex fluoroquinolone derivatives.
• Clinical Trial Materials: Supplied as a high-purity compound for pre-clinical and clinical studies evaluating new antibacterial therapies.
