Used primarily in organic synthesis, it serves as a key reagent for the formation of nitroxyl radicals, which are essential in studying free radical chemistry. It is also employed in the preparation of stable nitroxide compounds, widely utilized in spin labeling and electron paramagnetic resonance (EPR) spectroscopy. Additionally, it finds application in the development of pharmaceuticals and agrochemicals, where it aids in the synthesis of intermediates with potential biological activity. Its role in polymer chemistry is notable, contributing to the stabilization of polymers against degradation.
