Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and serotonin receptor modulators. Its enantiomeric purity makes it valuable for creating active pharmaceutical ingredients with high selectivity and reduced side effects. Commonly employed in asymmetric synthesis to introduce stereochemically defined amine functionality into complex molecules. Also utilized in the preparation of intermediates for antidepressants and antipsychotic drugs.
