Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active agents. Its structure supports modification for enhanced binding to serotonin and dopamine receptors. Commonly employed in medicinal chemistry for constructing indole-based drug candidates with potential antidepressant, anxiolytic, or antipsychotic activity. Also utilized in the preparation of kinase inhibitors and PET tracer molecules for neuroimaging studies.
