Description

Application

5,5-Dimethyl-1-pyrroline N-oxide is a reagent generally used either as a free-radical spin-trapping agent, or electrophilic component during the synthesis of pyrrolidine derivatives. It may also be considered as 1,3-dipole in cycloaddition processes.

Neuroprotective agent; nitric oxide spin trap. Used to study radicals formed by enzymatic acetaldehyde oxidation.

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.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
