Spin Trapping Reagent
Utilised in electron spin resonance (ESR) spectroscopy to detect and characterise short-lived free radicals. The dimer readily dissociates to the monomeric nitroso compound, which then reacts with radicals to form stable adducts detectable by ESR.
Chemical Synthesis
Serves as a precursor or reagent in organic synthesis, particularly in reactions involving radical intermediates or the introduction of nitroso functionalities. Its controlled dissociation allows for precise reaction management.
Research and Development
An important compound for academic and industrial R&D, enabling studies in reaction mechanisms, material science, and biological systems where radical processes are involved.
