Used in pharmaceutical research as an intermediate in the synthesis of bioactive compounds, particularly those targeting neurological and inflammatory pathways. Its indole core structure supports activity in modulating receptor functions, making it valuable in developing serotonin receptor ligands. Also employed in the preparation of analogs for structure-activity relationship (SAR) studies in drug discovery. Additionally, it serves as a building block in the synthesis of more complex heterocyclic systems for potential anticancer and antimicrobial agents.
