4,4′-dibromo-2,2′-bipyridine CAS: 18511-71-2

Name: 4,4′-dibromo-2,2′-bipyridine Other name: 2,2'-Bipyridine, 4,4'-dibromo-; 4,4′-dibromo-2,2′- dipyridine;4,4'-Dibromo-2,2'-bipyridyl; 4-bromo-2-(4-bromo(2- pyridyl))pyridine CAS: 18511-71-2 FW: C10H6Br2N2 Molecular weight: 313.97 Melting point: 139-141oC Appearance: white powder Purity: 98%min.(HPLC) Package: 100g, 500g, 1Kg, or bulk package 4,4′-Dibromo-2,2′-bipyridine is a key intermediate to make other 4,4’-synmmetric substituted-2,2’-bipyridine to enhance the absorption coefficient of the MLCT band by increasing the conjugation length of the ancillary ligand of the bipyridine scalefold. These activities have been produced many kinds of bipyridine ligands applied for DSSC, OFET, sensor, and catylsts for polymerization.
