Used in pharmaceutical synthesis as a key building block for active pharmaceutical ingredients (APIs), particularly in drugs targeting central nervous system disorders. Its structure enhances metabolic stability and bioavailability, making it valuable in the development of antidepressants, antipsychotics, and analgesics. Also employed in agrochemicals for the creation of novel pesticides due to the electron-withdrawing trifluoromethyl group improving compound resilience. Common in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug candidates.
