Description

(1S 2R 5S)-(+)-Menthyl (R)-p-Toluene- CAS NO 50444-99-0 is a high-purity, chiral auxiliary and resolving agent derived from menthol. This compound is critically important for its role in asymmetric synthesis, enabling the separation of enantiomers and the production of optically active intermediates. It is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries for developing chiral active pharmaceutical ingredients (APIs) and specialty chemicals.

Application

• Chiral Resolution Agent: Used for the separation of racemic mixtures of carboxylic acids and other acidic compounds.
• Asymmetric Synthesis: Serves as a key chiral auxiliary in stereoselective reactions to construct molecules with defined three-dimensional configurations.
• Pharmaceutical Intermediate: Employed in the research and production of enantiomerically pure drug candidates and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Utilized in the development of chiral pesticides and herbicides where specific stereochemistry is required for biological activity.
• Fine Chemical Production: Applied in the manufacture of specialty chemicals, flavors, and fragrances that require high optical purity.
• Academic & Industrial Research: A valuable tool in organic chemistry laboratories for methodological development and complex molecule synthesis.
