Description

Tilmicosin CAS NO 108050-54-0 is a semi-synthetic macrolide antibiotic derived from tylosin, specifically developed for veterinary medicine. Its primary value lies in its potent activity against key respiratory pathogens in livestock, offering a long-acting therapeutic effect that reduces the frequency of administration. This product is essential for manufacturers of veterinary pharmaceuticals and feed additives targeting the poultry, swine, and cattle industries to control and treat conditions like bovine respiratory disease and mycoplasmosis.

Application

• Veterinary Pharmaceutical Formulations: Primary active ingredient in injectable solutions and premixes for the treatment of respiratory infections.
• Poultry Health Management: Used to control and treat chronic respiratory disease (CRD) caused by *Mycoplasma gallisepticum* in chickens and turkeys.
• Swine Respiratory Disease Control: Effective against pathogens involved in porcine respiratory disease complex (PRDC).
• Cattle and Dairy Herd Health: Key therapeutic for bovine respiratory disease (BRD), also known as shipping fever.
• Feed Additive Production: Incorporated into medicated feed to promote growth and prevent disease outbreaks in herds and flocks.
• Aquaculture (Research & Development): Investigated for potential use in controlling bacterial infections in farmed fish.
• Reference Standard: Serves as a high-purity analytical standard for quality control testing in regulatory and laboratory settings.

Quality Control

Our Tilmicosin is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. The product undergoes rigorous analytical testing, including HPLC for assay and purity, identification by IR spectroscopy, and control of related substances and residual solvents. A comprehensive Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment 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.
