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 indole core structure makes it valuable in medicinal chemistry for designing compounds with biological activity. Commonly employed in research settings to construct more complex molecules for drug discovery, especially in treatments targeting neurological disorders. Also utilized in the preparation of analogs for structure-activity relationship (SAR) studies due to its functional groups that allow for further chemical modifications.
