Description

Florfenicol CAS NO 73231-34-2 is a broad-spectrum, fluorinated synthetic antibiotic belonging to the phenicol class. It is a critical veterinary pharmaceutical active ingredient specifically developed to overcome bacterial resistance mechanisms associated with chloramphenicol and thiamphenicol. This compound is essential for manufacturers in the animal health industry, primarily for the formulation of medicated feed, premixes, and injectable solutions to control bacterial respiratory and enteric diseases in livestock and aquaculture.

Application

• Veterinary Pharmaceuticals: Primary active ingredient in injectable solutions and oral formulations for cattle, swine, and poultry.
• Aquaculture Health Management: Key component in medicated feed for controlling bacterial diseases in farmed fish and shrimp, such as furunculosis and columnaris.
• Medicated Feed Additives: Used in the production of premixes and finished feeds for the prevention and treatment of respiratory and gastrointestinal infections.
• Veterinary Drug Intermediates: Serves as a crucial intermediate for synthesizing more advanced veterinary antibiotic formulations.
• Research & Development: Used in microbiological and pharmacological research to study antibiotic efficacy and resistance patterns.

Quality Control

Our Florfenicol is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and related substances, residual solvent analysis, and microbiological examination. A Certificate of Analysis (COA) detailing all test results against relevant pharmacopoeial or in-house specifications is provided with every shipment to guarantee compliance for veterinary pharmaceutical applications.

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). The product is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent degradation. Keep away from strong acids, bases, and oxidizing agents.
