Description

Pazufloxacin is a synthetic fluoroquinolone antibiotic known for its broad-spectrum antibacterial activity. It is a critical active pharmaceutical ingredient (API) valued for its efficacy against a wide range of Gram-positive and Gram-negative pathogens. This compound is essential for pharmaceutical manufacturers developing advanced antibacterial formulations, particularly for ophthalmic and injectable solutions.

Application

• Pharmaceutical API: Primary use as the active ingredient in the synthesis of antibacterial medications.
• Ophthalmic Solutions: Formulation into eye drops and ointments for treating bacterial conjunctivitis and other eye infections.
• Injectable Formulations: Production of sterile injectable products for systemic bacterial infections.
• Veterinary Medicine: Development of antibacterial treatments for veterinary applications.
• Research & Development: Used as a reference standard and in preclinical studies for new antibiotic research.
• Intermediate Synthesis: Serves as a key intermediate in the production of more complex fluoroquinolone derivatives.

Quality Control

Our Pazufloxacin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical use. We provide Certificates of Analysis (COA) with detailed results for parameters including assay, related substances, residual solvents, and microbiological quality, supporting compliance with cGMP and ICH guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
