Description

Ciprofloxacin CAS NO 85721-33-1 is a synthetic broad-spectrum fluoroquinolone antibiotic of significant pharmaceutical importance. It is valued for its potent bactericidal activity against a wide range of Gram-positive and Gram-negative pathogens. This active pharmaceutical ingredient (API) is essential for manufacturers in the pharmaceutical industry, primarily for the formulation of oral and injectable antibiotic medications to treat serious bacterial infections.

Application

• Pharmaceutical API: Primary use as the active ingredient in the manufacture of finished dosage forms, including tablets, capsules, and intravenous solutions.
• Antibacterial Formulations: Formulation into ophthalmic solutions and ointments for treating bacterial conjunctivitis and corneal ulcers.
• Veterinary Medicine: Used in veterinary pharmaceuticals to treat bacterial infections in livestock and companion animals.
• Research & Development: Serves as a critical reference standard and intermediate in microbiological research and the development of new antibacterial agents.
• Hospital & Clinical Use: Essential for compounding pharmacies and hospital settings for preparing specific patient-centric treatments.
