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. Employed in research related to central nervous system disorders due to its structural similarity to indole alkaloids. Also utilized in the preparation of fluorescent probes and imaging agents owing to the indole core’s photophysical properties. Common in medicinal chemistry for structure-activity relationship studies targeting neurological and psychiatric conditions.
