Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of antidiabetic and antiviral drugs. Its trifluoromethyl group enhances metabolic stability and bioavailability in drug candidates. Also employed in agrochemicals to improve the efficacy and environmental resistance of active ingredients. Commonly utilized in organic synthesis for introducing fluorinated moieties into complex molecules due to its reactive keto and carboxylic acid functional groups.
