Application

Free-radical nitroxide spin probe typically used for: Redox sources for anodes in lithium secondary batteries Free-radical biological studies Radical spin-trapping Electron paramagnetic resonance studies Polymer chemisty and synthesis applications

4-Oxo-TEMPO was employed as nitroxide standard to investigate the generation of singlet oxygen by photoexcited TiO₂ in ethanol by ESR spectroscopy. It may be employed as free radical polarizing agent in dynamic nuclear polarization (DNP) studies.

General description

4-Oxo-TEMPO is formed by the reaction of 2,2,6,6-tetramethyl-4-piperidone (4-oxo-TMP) and ¹O₂. It is a stable paramagnetic product formed during the irradiation of TiO₂ in aqueous suspensions.
