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 fluorinated aromatic structure and chiral amine functionality enhance binding selectivity and metabolic stability in drug candidates. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) for antidepressant and anxiolytic medications. The hydrochloride salt form improves crystallinity and handling during manufacturing processes.
