  • Applications

    Disodium cis-endo-bicyclo(2.2.1)heptane-2,3-dicarboxylate (CAS 351870-33-2) is typically used as an intermediate in the synthesis of specialty chemicals in industrial manufacturing. It may function as a metal-chelating/sequestering agent in polymer, coating, and cleaning formulations, helping stabilize systems and reduce metal-catalyzed degradation. In polymer and coating systems, it can serve as a processing aid or precursor for further functionalization to improve resin stability and performance. It is occasionally evaluated as a building block for ligands or other reagents in catalytic or pharmaceutical synthetic routes. Use depends on local regulations and formulation limits.
