DEPMPO
(Synonyms: 5-(二乙氧基磷酰)-5-甲基-1-吡咯啉-N-氧化物,5-(Diethoxyphosphoryl)-5-methyl-1-pyrroline-N-oxide) 目录号 : GC43410A spin trap for superoxide radical detection
Cas No.:157230-67-6
Sample solution is provided at 25 µL, 10mM.
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. [1] [2] [3] DEPMPO displays a detectable spin adduct signal at a concentration as low as 1 mM, as compared to 5 mM for DMPO.[3] 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.
