Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-heteroatom and carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boronate ester group facilitates efficient coupling under mild conditions, making it valuable in the development of complex nitrogen-containing heterocycles. The sulfonamide moiety enhances solubility and stability during reaction processes, supporting its use in high-yield transformations for drug discovery and materials science.
