Used as an intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki and Heck reactions, to construct complex aromatic systems for pharmaceuticals and functional materials. Its brominated structure allows for selective functionalization, making it valuable in the development of organic semiconductors, fluorescent dyes, and bioactive molecules. The sulfone group enhances electron-withdrawing properties, which can influence the electronic characteristics of conjugated systems in optoelectronic applications.
