Diphenic Acid（Cat No.:R070553）, also known as biphenyl-2,2′-dicarboxylic acid, is an aromatic dicarboxylic acid composed of two benzene rings connected at the 2-position, each bearing a carboxylic acid group. It is widely used as a building block in organic synthesis, particularly in the development of ligands, coordination complexes, and functional materials. Diphenic acid’s rigid, planar structure and dual acidity make it suitable for supramolecular chemistry, polymer design, and pharmaceutical intermediate synthesis. Supplied at high purity, it is ideal for research in materials science, catalysis, and advanced synthetic chemistry.
