Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system (CNS) active agents. Its structure supports the formation of carbazole-based derivatives known for biological activity in neurological and psychiatric disorders. Also employed in research for developing novel anti-inflammatory and anticancer compounds due to its ability to interact with cellular signaling pathways. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving heterocyclic compounds.
