Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Shows potential in medicinal chemistry due to structural similarity to serotonin and other indole alkaloids. Employed in research on receptor ligands, particularly in studies involving neurological pathways. Also utilized in the development of fluorescent probes and imaging agents because of its indole core, which can be modified for specific detection in biological systems. Commonly involved in cross-coupling reactions to build complex heterocyclic systems for drug discovery.
