Used in organic synthesis as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds for constructing complex indolinone derivatives. Its boronate ester group facilitates palladium-catalyzed coupling with aryl or heteroaryl halides, making it valuable in pharmaceutical and agrochemical research for developing bioactive molecules. Commonly employed in medicinal chemistry to build libraries of compounds targeting kinase inhibitors and other therapeutic agents.
