Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system agents. Its structure supports the construction of complex indole-based molecules, making it valuable in medicinal chemistry for drug discovery. Commonly employed in research settings to build novel compounds with potential antidepressant, anxiolytic, or antipsychotic activity. Also utilized in the preparation of kinase inhibitors and other biologically active heterocycles.
