Description

4,4′-([2,2′-Bipyridine]-4,4′-diyl)dibutanoic acid (CAS No. 447450-80-8) is a high-purity bipyridine derivative with a molecular formula of C₁₈H₂₀N₂O₄. This compound features a symmetrical structure with two carboxylic acid-terminated butyl chains attached to the 4 and 4′ positions of a 2,2′-bipyridine core, making it an excellent linker or building block for coordination chemistry, metal-organic frameworks (MOFs), and supramolecular assemblies. Its rigid bipyridine moiety provides strong chelating properties for transition metals, while the flexible carboxylic acid groups enable covalent or non-covalent functionalization. This product is ideal for researchers developing luminescent materials, catalysts, or sensors due to its electron-accepting and π-conjugated characteristics. Available in >95% purity (HPLC), it is supplied as a light-sensitive solid with strict storage recommendations (2-8°C under inert atmosphere). Each batch undergoes rigorous QC including ¹H NMR and LC-MS analysis to ensure reproducibility for your most demanding applications.
