Used primarily in organic synthesis as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical development. Its indole core with a boronate ester group allows for efficient coupling with aryl halides, making it valuable in constructing complex molecules for drug discovery. Commonly employed in the synthesis of bioactive compounds and functional materials due to its stability and reactivity under palladium catalysis.
