Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biaryl compounds, particularly in pharmaceutical and agrochemical research. Its boronic acid group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in drug discovery for constructing complex heterocyclic systems. The methylsulfonyl group enhances solubility and can act as a hydrogen bond acceptor, influencing the biological activity of target molecules. Commonly employed in the development of kinase inhibitors and other bioactive agents.
