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 neurological research agents. Employed in the study of indole-based amines for potential psychotropic and neuroprotective effects. Also applied in the preparation of fluorescent probes and dyes due to its indole scaffold, which exhibits favorable photophysical properties. Commonly utilized in medicinal chemistry for structure-activity relationship studies targeting central nervous system disorders.
