Used in pharmaceutical research as a key intermediate in the synthesis of serotonin receptor modulators. Shows potential in the development of central nervous system drugs, particularly for treating neurological disorders like depression and anxiety. Also employed in the preparation of fluorescent probes for biochemical imaging due to its indole backbone and favorable photophysical properties. Serves as a building block in the design of novel anticancer agents, where the vinyl and fluoro groups enhance reactivity and binding selectivity.
