Description

Turimycin Ep5 CAS NO 35908-44-2 is a high-purity macrolide antibiotic compound, also known as Tylosin Epimer V. This compound is a critical intermediate and reference standard in the pharmaceutical industry, valued for its role in quality control and research. It is primarily required by manufacturers and R&D facilities in the veterinary and human pharmaceutical sectors for the production, analysis, and development of antibiotic formulations.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification and quantification of Tylosin and related substances in quality control laboratories.
• Veterinary Drug Manufacturing: Serves as a key intermediate or starting material in the synthesis of medicated feed additives and injectable solutions for livestock.
• Analytical Research & Method Development: Essential for developing and validating chromatographic methods (HPLC, LC-MS) for antibiotic residue testing in food and environmental samples.
• Microbiological Studies: Employed in academic and industrial research to study the structure-activity relationships, efficacy, and resistance mechanisms of macrolide antibiotics.
• Active Pharmaceutical Ingredient (API) Synthesis: Used in the controlled production of Tylosin tartrate and other derivative forms for therapeutic use.
• Regulatory Compliance & Documentation: Provides essential material for generating impurity profiles and stability data required for regulatory filings (e.g., FDA, EMA dossiers).
