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 due to the presence of both amino and hydroxyl functional groups in a stereochemically defined arrangement. Commonly employed in the production of antidepressants and anxiolytic drugs, where the (S)-configuration plays a critical role in pharmacological activity. The trifluoromethylphenyl moiety enhances metabolic stability and lipophilicity, improving blood-brain barrier penetration. Also utilized in asymmetric synthesis and catalysis research due to its rigid backbone and stereogenic center.
