Used as an intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biaryl compounds in pharmaceutical and agrochemical research. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions. Commonly applied in the development of sulfonamide-based bioactive molecules, including kinase inhibitors and antifungal agents. Valued for its stability and reactivity in palladium-catalyzed transformations during drug discovery.
