Description

Oxiranecarboxylic Acid, 1,1-Dimethylethyl Ester, (S)- (9Ci) is a high-value chiral building block and protected glycidic acid derivative, essential for the stereoselective synthesis of complex organic molecules. Its primary value lies in providing a reactive, enantiomerically pure epoxide moiety that can be selectively opened by various nucleophiles under controlled conditions. This compound is critically needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for constructing active pharmaceutical ingredients (APIs), advanced intermediates, and novel bioactive compounds.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of β-blockers, protease inhibitors, and other enantiomerically pure drugs.
• Agrochemical Synthesis: Building block for creating chiral herbicides, fungicides, and plant growth regulators with enhanced activity.
• Fine Chemical Production: Used in the preparation of specialty chemicals, flavors, fragrances, and advanced materials requiring specific stereochemistry.
• Asymmetric Synthesis: Serves as a versatile electrophile in stereocontrolled ring-opening reactions to introduce hydroxy and other functional groups.
• Academic & Industrial R&D: A valuable reagent for methodological development in organic chemistry and catalysis research.
• Peptide Mimetic Construction: Used to incorporate non-natural amino acid residues or other chiral elements into peptide backbones.
