Description
5,5′-Dibromo-2,2′-bipyridine (CAS No. 15862-18-7) is a high-purity halogenated bipyridine compound with the molecular formula C10H6Br2N2. This heterocyclic aromatic compound features two pyridine rings bridged at the 2,2′-positions, each substituted with a bromine atom at the 5-position, offering exceptional reactivity for cross-coupling reactions and metal coordination. Its rigid planar structure and electron-deficient nature make it a valuable ligand in catalysis, supramolecular chemistry, and materials science. Supplied as a crystalline solid with ≥95% purity (HPLC), it is ideal for synthesizing transition metal complexes, organic semiconductors, and pharmaceutical intermediates. Store in a cool, dry place under inert conditions to ensure stability.

Application
5,5′-Dibromo-2,2′-bipyridine serves as a key precursor in Suzuki-Miyaura and Stille cross-coupling reactions to construct conjugated polymers for OLEDs. It is widely employed as a chelating ligand for ruthenium and iridium complexes in photoredox catalysis. Researchers also utilize it to develop metal-organic frameworks (MOFs) with tailored luminescent properties.
