Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. Its structure supports the development of sulfone-based molecules with potential antitumor and anti-inflammatory properties. The boronate ester group enables cross-coupling reactions, making it valuable in medicinal chemistry for building complex aromatic systems. Commonly employed in Suzuki-Miyaura coupling to create novel drug candidates. Also utilized in the preparation of kinase inhibitors and other targeted therapies in oncology research.
