Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active agents. Its cyclopropyl structure with a trifluoromethylphenyl group enhances metabolic stability and lipophilicity, making it valuable in drug design for improving bioavailability and blood-brain barrier penetration. Commonly employed in the preparation of antidepressants, anticonvulsants, and other neuroactive compounds. Also utilized in agrochemical research for building blocks requiring enhanced stability and specific stereochemistry.
