Used in pharmaceutical research as an intermediate in the synthesis of biologically active compounds, particularly in the development of serotonin receptor modulators and anti-inflammatory agents. Its structure serves as a building block for indole-based molecules, which are common in drug discovery due to their affinity for various biological targets. Also employed in the preparation of kinase inhibitors and antitumor agents in experimental oncology. Common in medicinal chemistry for structure-activity relationship (SAR) studies involving substituted indoles.
