Used in pharmaceutical synthesis as a key intermediate for developing central nervous system (CNS) active compounds. Its structure supports the design of ligands targeting neurotransmitter receptors, particularly serotonin and dopamine receptors. Commonly employed in the development of experimental antidepressants and antipsychotics due to the presence of the trifluoromethylphenyl group, which enhances blood-brain barrier penetration and metabolic stability. Also utilized in structure-activity relationship (SAR) studies to optimize potency and selectivity in novel drug candidates.
