Used as a ligand in coordination chemistry to stabilize metal complexes, particularly in catalytic reactions. It is employed in cross-coupling reactions, such as Suzuki-Miyaura and Heck reactions, to facilitate the formation of carbon-carbon bonds. Its electron-rich nature enhances the efficiency of palladium and other transition metal catalysts. Additionally, it finds application in organic synthesis for constructing complex molecular architectures, including pharmaceuticals and fine chemicals. Its brominated aromatic groups contribute to its stability and reactivity in various chemical transformations.
