LUN76721 has CAS#4376-72-1, is a cyclophosphazene and a useful chemical reagent. Cyclophosphazenes have been studied among others as flame retardant additives, high temperature fluids, clathrates, photostabilizers, or antioxidants in organic polymers. Cyclophosphazenes have also been used as phase transfer catalysts, as polypodants and cryptands. Cyclophosphazenes have also been successfully used as biologically active agents. Moreover cyclotriphosphazenes, were used for polymer functionalization and synthesis, as pendant groups or monomers for polyphosphazene synthesis, especially those bearing six chlorine atoms or phenoxy groups.
