DEPMPO,cas:157230-67-6

DEPMPO(C9H18NO4P,235.2) is a phosphorylated derivative of the widely used DMPO spin trap. It has been reported to produce spin adducts with increased stability particularly for the adduct of superoxide. DEPMPO displays a detectable spin adduct signal at a concentration as low as 1 mM, as compared to 5 mM for DMPO.A significant advantage of using DEPMPO in trapping superoxide radical is that the decomposition of DEPMPO/O2•- does not produce the OH• adduct, which can be a drawback when using DMPO.
