Used as a key 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 chiral structure makes it valuable for creating enantiomerically pure drugs, improving efficacy and reducing side effects. Commonly employed in research and development for neuropharmacological treatments, including antidepressants and anxiolytics. Also utilized in the preparation of radiolabeled derivatives for use in positron emission tomography (PET) imaging studies targeting serotonin receptors in the brain.
