Used as a key intermediate 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 agrochemical research for constructing biaryl structures. Its boronate ester group facilitates mild and selective coupling with aryl halides, making it valuable in late-stage functionalization of drug candidates. Also employed in materials science for designing organic semiconductors and functional polymers.
