Stable Nitroxide

Reverse phase high performance liquid chromatography coupled to electrospray ionisation mass spectrometry and tandem mass spectrometry has allowed quantitative measurement of a stable nitroxide, 4-hydroxy-2,2,6,6-tetramethyl-piperidine-N-oxyl (4-hydroxy-tempo), the latter with high sensitivity.
