Used primarily in organic synthesis as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical development. The boronate ester group facilitates coupling with aryl halides under palladium catalysis, making it valuable in constructing complex aromatic systems. Its sulfonamide moiety enhances solubility and binding properties, useful in medicinal chemistry for designing bioactive molecules. Commonly employed in the synthesis of functionalized anilines and in materials science for creating conjugated systems.
