Description

Marbofloxacin CAS NO 115550-35-1 is a synthetic, broad-spectrum fluoroquinolone antibiotic belonging to the third generation of this important class. It is valued for its potent bactericidal activity against a wide range of Gram-positive and Gram-negative pathogens. This compound is primarily utilized in the veterinary pharmaceutical industry for the development of effective treatments for bacterial infections in companion and food-producing animals.

Application

• Veterinary Pharmaceutical Formulations: As the active pharmaceutical ingredient (API) in injectable solutions, tablets, and oral suspensions for treating bacterial diseases in dogs, cats, and cattle.
• Treatment of Respiratory Infections: Specifically indicated for bovine respiratory disease (BRD) and canine/cat upper respiratory tract infections caused by susceptible organisms.
• Management of Skin and Soft Tissue Infections: Used in topical and systemic formulations for pyoderma, wound infections, and abscesses in companion animals.
• Urinary Tract Infection (UTI) Therapy: Effective against common uropathogens in veterinary medicine.
• Research & Development: Serves as a key reference standard and intermediate in antimicrobial research and the development of new veterinary medicinal products.
• Aquaculture Applications: Investigated for use in controlling bacterial infections in farmed fish, subject to regional regulatory approvals.

Quality Control

Our Marbofloxacin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical use. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and impurity profiles as per in-house specifications aligned with veterinary pharmacopoeial expectations.

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 nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture.
