Used as a brominated aromatic intermediate in organic synthesis. Commonly applied as a precursor for the preparation of substituted biphenyl compounds, pharmaceutical intermediates, organic electronic materials, and functional aromatic molecules. It is also used as a starting material in palladium-catalyzed cross-coupling reactions such as Suzuki, Heck, and related transformations.
