Used as a key chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its chiral amine functionality allows for selective interactions in drug molecules, enhancing potency and reducing side effects. Commonly employed in the development of serotonin and dopamine receptor modulators. Also utilized in asymmetric synthesis due to the stereochemical purity of the (S)-enantiomer, enabling precise construction of complex medicinal agents.
