Description

Florfenicol is a synthetic, broad-spectrum antibiotic belonging to the phenicol class, specifically developed for veterinary use. Its primary value lies in its efficacy against bacterial pathogens that have developed resistance to other antibiotics, such as chloramphenicol and thiamphenicol. This makes it a critical active pharmaceutical ingredient (API) for manufacturers in the animal health industry, particularly for treating respiratory and enteric diseases in livestock, aquaculture, and companion animals.

Application

• Veterinary Pharmaceutical Formulations: Primary use as an API in injectable solutions, oral powders, premixes, and medicated feed additives for cattle, swine, poultry, and sheep.
• Aquaculture Health Management: Key component in medicated feeds and bath treatments to control bacterial infections in farmed fish and shrimp, such as furunculosis and columnaris disease.
• Companion Animal Medicine: Used in topical preparations (e.g., ear and eye drops) and systemic treatments for dogs and cats under veterinary prescription.
• Poultry Industry: Administration via drinking water or feed to combat respiratory syndromes and other bacterial outbreaks in broilers and layers.
• Research & Development: Serves as a reference standard and raw material in pharmaceutical R&D for developing new veterinary therapeutics and studying antimicrobial resistance.

Quality Control

Our Florfenicol is manufactured under strict quality management systems to ensure it meets the high standards required for veterinary pharmaceutical applications. Each batch undergoes comprehensive analytical testing, including identification, assay, impurity profiling, and residual solvent analysis, typically via HPLC, IR, and other pharmacopoeial methods. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to guarantee supply reliability and batch-to-batch consistency.

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). This product is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent degradation. Keep away from incompatible materials.
