Description

Tylosin, 3-Acetate 4B-(3-Methylbutanoate) is a chemically modified derivative of the macrolide antibiotic tylosin, specifically engineered to enhance its stability and bioavailability. This compound is critical for applications requiring a more stable form of tylosin, particularly in veterinary medicine and animal health. It is primarily needed by manufacturers in the pharmaceutical and animal feed additive industries for the formulation of advanced therapeutic and prophylactic products.

Application

• Primary active pharmaceutical ingredient (API) in veterinary formulations for the treatment of bacterial infections in livestock and poultry.
• Key component in the production of medicated feed premixes and water-soluble powders for growth promotion and disease prevention.
• Used in research and development of new macrolide antibiotics and for studying bacterial resistance mechanisms.
• Intermediate in the synthesis of other tylosin derivatives with targeted pharmacological profiles.
• Reference standard in analytical laboratories for quality control and regulatory testing of tylosin-based products.

Quality Control

Our Tylosin, 3-Acetate 4B-(3-Methylbutanoate) is manufactured under strict quality systems to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical tests including HPLC, IR, and loss on drying. Certificates of Analysis (COA) documenting full compliance with in-house specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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.
