Used as an efficient nitroxyl radical precursor in organic synthesis, particularly in oxidation reactions. It serves as a key reagent in catalytic systems for the selective oxidation of alcohols to carbonyl compounds under mild conditions. Its stability and reactivity make it valuable in the development of environmentally friendly oxidation processes. Also applied in polymer chemistry as a mediator in controlled radical polymerizations, enhancing control over molecular weight and polydispersity. Additionally, it has shown utility in biochemical assays involving radical trapping and spin-labeling techniques.
