Description: 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.

Additional Information

Cyclotriphosphazenes, are considered as one of the most interesting and oldest group of inorganic phosphorus and nitrogen heterocyclic compounds with general formula N3P3R6, where R can be a chlorine atom or an organic group bonded to the phosphorus. The origins of research on the synthesis, properties and applications of this group of compounds dates back to the mid-nineteenth century when Liebig and Rose used phosphorus pentachloride and ammonia to obtain the first known cyclic phosphazene trimer.
