Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. Its structure supports the design of molecules with potential anxiolytic, antidepressant, or antipsychotic activity. The compound's trifluoromethyl group enhances metabolic stability and membrane permeability, making it valuable in optimizing drug candidates. It is also employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid heterocyclic core and ability to engage in hydrogen bonding and dipole interactions.
