Description

Oxiranecarboxylic Acid, 3-Methyl-, 1-Methylethyl Ester, (2R,3S)-Rel- (9Ci) is a high-purity, stereochemically defined chiral building block, specifically the isopropyl ester of a methyl-substituted glycidic acid. This compound is valued for its role as a versatile synthetic intermediate in the production of complex, optically active molecules. It is primarily needed by research and development laboratories and production facilities in the pharmaceutical and agrochemical industries for the synthesis of active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in routes requiring the introduction of a functionalized epoxide moiety.
• Agrochemical Synthesis: Used in the research and production of advanced, stereospecific pesticides and herbicides.
• Fine Chemical Production: Serves as a building block for specialty chemicals, flavors, and fragrances where specific stereochemistry is critical.
• Asymmetric Synthesis: Employed in academic and industrial research for developing new catalytic and stoichiometric asymmetric transformations.
• Material Science Research: Potential monomer or cross-linking agent in the development of specialized polymers with tailored properties.
