Used primarily in pharmaceutical research as a key intermediate in the synthesis of selective serotonin reuptake inhibitors (SSRIs) and related antidepressant drugs. Its chiral structure makes it valuable for developing enantiomerically pure compounds with improved efficacy and reduced side effects. It is also investigated for potential applications in neuropharmacology due to its structural similarity to serotonin and melatonin, supporting studies on mood regulation, sleep disorders, and cognitive function. Additionally, it serves as a building block in the development of receptor agonists and antagonists targeting central nervous system disorders.
