Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for central nervous system (CNS) drugs. It serves as a building block in the production of selective serotonin reuptake inhibitors (SSRIs) and related antidepressants due to its ability to modulate neurotransmitter activity. Its trifluoromethyl group enhances metabolic stability and bioavailability in final drug compounds. Also employed in the preparation of agrochemicals and specialty polymers where thermal and chemical resistance are required.
