This chemical is primarily utilized as a stable radical in various scientific and industrial applications. It is often employed as a spin label in electron paramagnetic resonance (EPR) spectroscopy to study the structure and dynamics of complex molecules, such as proteins and polymers. Its stable radical nature allows it to act as a probe, providing insights into molecular interactions and conformational changes. Additionally, it is used in organic synthesis as a mediator in oxidation reactions, facilitating the selective oxidation of alcohols and other substrates. Its role in polymerization processes is also notable, where it can act as a control agent in nitroxide-mediated radical polymerization (NMP), enabling the production of well-defined polymers with specific properties.
