Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development 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 asymmetric synthesis routes where the amine functionality allows for coupling reactions or ring formation. Also utilized in the preparation of bioactive molecules targeting neurological disorders due to its structural similarity to neurotransmitter analogs. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous or polar reaction media during drug manufacturing.
