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 participates in palladium-catalyzed coupling with aryl halides, making it valuable for constructing biaryl systems found in active pharmaceutical ingredients. The tert-butyl sulfonamide group enhances stability and influences solubility, aiding in purification and handling during multi-step syntheses. Commonly employed in research and development of new drug candidates and functional materials.
