Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boron-containing structure allows efficient coupling with aryl halides under palladium catalysis, making it valuable in the development of complex organic molecules, particularly in drug discovery and materials science. The methylsulfonyl group enhances reactivity and directs regioselectivity, improving yield and selectivity in synthetic pathways.
