Description

Tylosin Tartrate CAS NO 1405-54-5 is a macrolide antibiotic salt, specifically the tartrate form of tylosin, which enhances its stability and solubility. This compound is valued for its potent antibacterial activity against Gram-positive organisms and mycoplasmas. It is a critical active pharmaceutical ingredient (API) primarily required by manufacturers in the veterinary pharmaceutical and animal feed additive industries.

Application

• Primary use as an active pharmaceutical ingredient (API) in veterinary injectable and oral formulations.
• Manufacture of medicated premixes for inclusion in animal feed to promote growth and prevent disease.
• Treatment and control of respiratory diseases (e.g., swine enzootic pneumonia) and other infections in livestock.
• Used in poultry for the prevention and treatment of chronic respiratory disease (CRD) caused by *Mycoplasma gallisepticum*.
• Key component in veterinary medicinal products for swine, cattle, and poultry.
• Research and development of new antibacterial formulations within the animal health sector.

Quality Control

Our Tylosin Tartrate is manufactured under strict quality management systems to ensure it meets the high standards required for pharmaceutical use. Each batch undergoes comprehensive analytical testing, including identification, assay, and impurity profiling via HPLC. Certificates of Analysis (COA) documenting compliance with relevant 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 controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to protect from moisture.
