Used as a key chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure supports the development of agents with enhanced selectivity and binding affinity to neurotransmitter receptors. Commonly employed in the production of antidepressants and anxiolytic drugs due to its ability to influence serotonergic and noradrenergic pathways. The presence of trifluoromethyl group enhances metabolic stability and lipophilicity, improving blood-brain barrier penetration. Also utilized in asymmetric synthesis for constructing complex molecules requiring high enantiomeric purity.
