Chemical Structure
Description
The occurrence of 4,4'-([2,2'-Bipyridine]-5,5'-diyl)dibenzoic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,4'-([2,2'-Bipyridine]-5,5'-diyl)dibenzoic acid (CAS 1373759-05-7) is a high-purity analytical reference standard with the molecular formula C24H16N2O4 and a molecular weight of 396.39 g/mol.
4,4'-([2,2'-Bipyridine]-5,5'-diyl)dibenzoic acid (C24H16N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
