  • Applications

    CU4-From florida state university (CAS 75628-11-4) is a tetranuclear copper cluster commonly used as a catalyst precursor and a building block for coordination polymers. In practice, its applications are largely in research and development, including use as a catalyst precursor for copper-catalyzed transformations in organic synthesis, as a component in copper-containing coordination polymers or MOF-like materials for functional coatings or electronic applications, and as an active material or precursor in electrochemical devices and energy storage research. It may also serve as an intermediate in the synthesis of copper-containing polymers or composites and as a reference system in spectroscopic studies; usage is subject to local regulations and formulation limits.
