Description

Tosufloxacin Tosilate CAS NO 107097-79-0 is the tosylate salt form of tosufloxacin, a broad-spectrum fluoroquinolone antibiotic. This active pharmaceutical ingredient (API) is critical for its potent antibacterial activity against a wide range of Gram-positive and Gram-negative pathogens. It is primarily required by pharmaceutical manufacturers for the formulation of advanced antibiotic drugs, targeting complex respiratory, skin, and soft tissue infections.

Application

• Pharmaceutical API: Primary use as the active ingredient in the synthesis of finished antibiotic dosage forms, such as tablets and capsules.
• Respiratory Infection Treatments: Formulation of medications targeting bronchitis, pneumonia, and other bacterial respiratory tract infections.
• Dermatological Preparations: Used in topical or systemic treatments for bacterial skin and soft tissue infections.
• Ophthalmic Solutions: Potential use in the development of eye drop formulations for bacterial conjunctivitis.
• Veterinary Medicine: Application in veterinary pharmaceuticals for treating bacterial infections in animals.
• Research & Development: Serves as a key reference standard and intermediate in antimicrobial research and new drug development projects.

Quality Control

Our Tosufloxacin Tosilate is manufactured under strict quality management systems. The product undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each batch to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
