Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of serotonin receptor modulators and neuropharmacological agents. Its structure supports the creation of complex indole-based molecules with potential antidepressant, antipsychotic, or anti-inflammatory activity. Also employed in the design of kinase inhibitors and other targeted therapies in oncology. Commonly utilized in medicinal chemistry for scaffold modification and structure-activity relationship (SAR) studies.
