Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the production of selective norepinephrine reuptake inhibitors. Its enantiomeric purity is critical for optimal biological activity in central nervous system therapeutics. Commonly employed in the development of antidepressants and anxiolytic drugs due to its role in enhancing neurotransmitter regulation. Also utilized in asymmetric synthesis routes where stereochemical control is essential for drug efficacy and safety.
