  • Applications

    Butyl 3-methyl-2-phenyloxirane-2-carboxylate is primarily employed as a synthetic intermediate in organic chemistry, providing a chiral epoxide motif that enables stereoselective ring-opening to furnish beta-hydroxy esters and other chiral building blocks used in pharmaceutical and fine-chemical synthesis. It can act as a reactive epoxide monomer or crosslinking component in epoxy resin formulations, coatings and adhesives, contributing to network formation and film properties. The ester and epoxide functionality also make it a potential precursor in specialty polymers and UV-curable systems. In fragrance and flavor chemistry, it is evaluated as a synthetic intermediate for aroma-related compounds. Depending on formulation, it may be used in electronics-grade coatings and potting resins where reactive epoxy functionality is advantageous.
