Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its boronate ester group readily transmetallates with palladium catalysts, making it valuable for constructing biaryl and extended aromatic systems found in pharmaceuticals, agrochemicals, and advanced materials. Commonly employed in the development of organic semiconductors, liquid crystals, and conjugated polymers due to its stability and reactivity profile. Also utilized in late-stage functionalization strategies in drug discovery for rapid structural diversification.
