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 enantiomeric purity is critical for achieving desired biological activity and minimizing side effects in final drug products. Commonly employed in asymmetric synthesis routes where the (R)-configuration enhances binding affinity to specific neurotransmitter targets. Also utilized in research settings for developing novel analogs in medicinal chemistry programs focused on antidepressants and anxiolytics.
