Used as a key intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals due to the presence of the trifluoromethyl group, which enhances metabolic stability and bioavailability. Its α,β-unsaturated ester structure allows participation in Michael additions and cycloaddition reactions, making it valuable in constructing complex organic molecules. Commonly employed in the development of active ingredients in crop protection agents and in medicinal chemistry for creating fluorinated analogs of biologically active compounds.
