Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Serves as a building block in the development of serotonin receptor modulators due to its structural similarity to tryptamine. Employed in research for neuropharmacology, particularly in studies related to central nervous system disorders. Also utilized in the preparation of fluorescent probes and functional materials in materials science. Common in cross-coupling reactions, such as Sonogashira, to expand indole-based molecular architectures for drug discovery.
