Used as a key intermediate 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 in constructing biaryl sulfonamide scaffolds found in bioactive molecules. Commonly employed in medicinal chemistry for lead optimization and library synthesis due to its stability and reactivity profile.
