Description

4,4′-([2,2′-Bipyridine]-5,5′-diyl)dibenzoic acid (CAS No. 1373759-05-7) is a high-purity, bipyridine-based organic compound with the molecular formula C₂₄H₁₆N₂O₄. This bifunctional aromatic carboxylic acid features a rigid 2,2′-bipyridine core flanked by two benzoic acid groups, making it an excellent building block for metal-organic frameworks (MOFs), coordination polymers, and supramolecular assemblies. Its IUPAC name is 4-[6-[5-(4-carboxyphenyl)pyridin-2-yl]pyridin-3-yl]benzoic acid. The compound exhibits strong chelating properties due to its bipyridine moiety and is widely used in catalysis, luminescent materials, and as a linker in porous materials research. Available in ≥95% purity (HPLC), it is supplied as a fine yellow powder with traceable analytical data (MS, NMR, FTIR). Store under inert conditions at 2-8°C.
