Used in pharmaceutical research as a key intermediate in the synthesis of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure supports binding to neurotransmitter receptors, making it valuable in developing antidepressants and anxiolytic drugs. Also explored for use in radiolabeled forms for receptor binding studies. Shows potential in the development of novel analgesics due to interaction with opioid receptor subtypes. Investigated for improved bioavailability and metabolic stability in oral formulations.
