Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex organic molecules. Commonly applied in pharmaceutical development and materials science for constructing biaryl structures. Its boronate ester group facilitates palladium-catalyzed coupling with aryl halides under mild conditions, making it valuable in late-stage functionalization of drug candidates. Also employed in the preparation of conjugated polymers and organic electronic materials due to its stability and reactivity profile.
