Description

Oxiranecarboxylic Acid, 3-Methyl-, 1-Methylethyl Ester, (2S,3R)- (9Ci) is a high-purity, stereochemically defined chiral epoxide derivative. This compound is a critical chiral building block and intermediate in advanced organic synthesis, valued for its ability to introduce specific stereochemistry into complex molecular frameworks. It is essential for research and production in the pharmaceutical and fine chemical industries, where precise stereochemical control is paramount for developing active pharmaceutical ingredients (APIs) and specialty agrochemicals.

Application

• Chiral Intermediate in Pharmaceutical Synthesis: A key building block for the production of enantiomerically pure active pharmaceutical ingredients (APIs), particularly in antiviral, anticancer, and cardiovascular drug development.
• Agrochemical Intermediate: Used in the synthesis of advanced, stereoselective pesticides and herbicides where biological activity is dependent on specific molecular configuration.
• Fine Chemical Synthesis: Serves as a versatile precursor for synthesizing complex natural products, flavors, fragrances, and other high-value specialty chemicals requiring defined stereochemistry.
• Asymmetric Catalysis Research: Employed as a standard substrate or ligand precursor in academic and industrial research focused on developing new asymmetric synthetic methodologies.
• Polymer Chemistry: Can be utilized as a monomer or cross-linking agent for creating polymers with specific chiral centers or for surface functionalization.
