Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure allows for high affinity binding to specific neuronal receptors, making it valuable in the production of antidepressant and anxiolytic drugs. The compound's chiral purity enhances the efficacy and safety profile of the final drug products. It is also employed in research settings for exploring new neuropharmacological treatments.
