Description

Chloramphenicollevobp CAS NO 9356-75-7 is a high-purity, single-enantiomer form of the broad-spectrum antibiotic chloramphenicol, specifically the levorotatory isomer. This compound is critical for applications requiring precise stereochemistry and minimized side-effect profiles compared to the racemic mixture. It is an essential intermediate and active pharmaceutical ingredient (API) for the research and development of advanced antimicrobial therapeutics. Industries requiring this material include pharmaceutical manufacturing, advanced chemical synthesis, and life science research.

Application

• Pharmaceutical API Synthesis: Serves as a key starting material or intermediate in the production of enantiomerically pure antibiotic formulations.
• Veterinary Medicine: Used in the development of targeted treatments for bacterial infections in animals.
• Biochemical Research: Employed as a standard or reagent in studies of bacterial protein synthesis inhibition and antibiotic resistance mechanisms.
• Reference Standard: Utilized as a high-purity calibrant in analytical laboratories for quality control of chloramphenicol-based products.
• Advanced Intermediate: Acts as a chiral building block for the synthesis of novel, more potent antimicrobial derivatives.
