Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Serves as a building block in the development of serotonin receptor modulators and other neuroactive agents. Commonly employed in research related to central nervous system disorders due to its structural similarity to tryptamine derivatives. Also utilized in the preparation of fluorescent probes and optoelectronic materials owing to its indole core and halogenated aromatic system. The bromine substituent allows further functionalization via cross-coupling reactions, making it valuable in medicinal chemistry for structure-activity relationship studies.
