Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system agents. It serves as a building block in medicinal chemistry for constructing indole-based compounds with potential antipsychotic, antidepressant, or anti-migraine activity. Its bromo and nitrile functional groups allow for further derivatization through cross-coupling reactions and nucleophilic additions, making it valuable in creating diverse compound libraries for drug discovery. Also employed in the preparation of fluorescent probes and agrochemicals due to its aromatic structure and reactivity.
