DEPMPO

DEPMPO 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 (Cay-10006436). 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.Formal Name: P-(3,4-dihydro-2-methyl-1-oxido-2H-pyrrol-2-yl)-phosphonic acid, diethyl ester.
