Used in the synthesis of pharmaceutical intermediates, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its chiral amine structure makes it valuable in asymmetric synthesis, where stereochemistry plays a critical role in drug efficacy. Commonly employed in research and development for novel antidepressants and anxiolytic compounds. Also utilized in the preparation of chiral ligands and catalysts for enantioselective reactions in medicinal chemistry.
