Application
2,2'-Dibromo-1,1'-biphenyl (CAS 13029-09-9) is a symmetrically ortho-substituted dibromobiphenyl widely used as a key intermediate in organic synthesis, particularly for cross-coupling reactions such as Suzuki-Miyaura, Stille, and Negishi couplings. The two bromine atoms allow sequential or simultaneous introduction of aryl, heteroaryl, or alkyl groups, enabling the construction of complex biphenyl scaffolds. It is extensively employed in the synthesis of chiral ligands (e.g., BINAP derivatives, phosphine ligands) for asymmetric catalysis, as well as in the preparation of pharmaceuticals, including antihypertensive and anticancer agents. In materials science, 2,2'-dibromobiphenyl serves as a monomer for polyfluorenes, OLED emitters, liquid crystal displays (LCDs), and conjugated polymers. It is also a precursor for carbazole-based and phenazine-based heterocycles via metal-catalyzed amination or C-H functionalization. High-purity grade ensures reproducible performance in sensitive catalytic and electronic applications.
