Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active compounds. Its stereochemistry plays a critical role in ensuring high enantioselectivity and biological activity in final drug products. Commonly employed in the development of antidepressants and anxiolytic drugs due to its ability to influence neurotransmitter regulation. Also utilized in research settings for the preparation of structurally complex amines and heterocyclic derivatives with potential therapeutic applications.
