Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boronate ester group facilitates palladium-catalyzed coupling with aryl halides, making it valuable for constructing complex aromatic systems. Commonly employed in late-stage functionalization of bioactive molecules due to its stability and reactivity profile. Also utilized in materials science for synthesizing conjugated organic frameworks and functionalized polymers.
