Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and central nervous system agents. Its trifluoromethyl group enhances metabolic stability and lipophilicity, making it valuable in medicinal chemistry for optimizing drug candidates. Also employed in agrochemical research for designing novel pesticides with improved efficacy and environmental profiles. Commonly utilized in structure-activity relationship (SAR) studies due to its ability to influence electronic and steric properties in heterocyclic compounds.
