Application

5,5-Dimethyl-1-pyrroline N-oxide has been used as a spin trapping reagent to detect free radicals in electron paramagnetic resonance (EPR) based reactions.
Neuroprotective agent; nitric oxide spin trap. Used to study radicals formed by enzymatic acetaldehyde oxidation. Incubation of lymphocytes with DMPO decreased DNA damage by NiCl2.

Free radicals are conventionally detected by electron paramagnetic resonance (EPR) spectroscopy after being trapped as spin adducts. Albeit this technique has demonstrated utmost efficacy in studying free radicals, its application to biological settings is intrinsically hampered by the inevitable bioreduction
