Description

Butanoic Acid, 2-(Benzoyloxy)-3-Methyl-, (R)- (9Ci) is a chiral, optically active ester derivative of butanoic acid, characterized by its specific stereochemistry at the R-configuration. This compound serves as a valuable chiral building block and intermediate in the synthesis of complex molecules where stereochemical control is paramount. It is primarily needed by research institutions and pharmaceutical companies engaged in the development of active pharmaceutical ingredients (APIs), agrochemicals, and advanced materials.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and production of enantiomerically pure drugs, particularly in stereoselective synthesis.
• Agrochemical Synthesis: Used in the development of chiral pesticides and herbicides where biological activity is stereospecific.
• Fine Chemical Production: Serves as a precursor for flavors, fragrances, and other specialty chemicals requiring defined stereochemistry.
• Academic & Industrial Research: Employed in methodological studies for asymmetric synthesis, catalysis, and the development of new synthetic routes.
• Liquid Crystal & Advanced Material Precursor: Potential use in the synthesis of chiral dopants and components for electronic displays and optical devices.
