Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. Its structural motif appears in certain neuroactive compounds, including some analgesics and dopamine receptor modulators. The (S)-enantiomer is often preferred for its stereoselective interaction with biological targets, enhancing efficacy and reducing side effects in drug candidates. Also employed in asymmetric synthesis and as a ligand precursor in catalytic reactions.
