[1,1'-Biphenyl]-3,3',4,4'-tetracarboxylic Acid (CAS 22803-05-0) is a biphenyl-based tetracarboxylic acid building block from TCI, widely employed as a polytopic organic linker for constructing Metal-Organic Frameworks (MOFs) and coordination polymers. Its four carboxylate groups enable strong multi-dentate coordination with metal clusters, making it a versatile precursor in porous crystalline materials research. This compound is commonly applied in studies involving gas adsorption, heterogeneous catalysis, and the synthesis of advanced functional materials.
