Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex indole derivatives. Its boronate ester group facilitates mild and selective coupling with aryl or heteroaryl halides, making it valuable in pharmaceutical and agrochemical research. Commonly employed in the development of bioactive molecules, including drug candidates targeting neurological disorders, inflammation, and cancer. Also utilized in materials science for constructing conjugated systems in organic electronics.
