General description
Application
4-Oxo-TEMPO was employed as nitroxide standard to investigate the generation of singlet oxygen by photoexcited TiO2 in ethanol by ESR spectroscopy.[1] It may be employed as free radical polarizing agent in dynamic nuclear polarization (DNP) studies.[3]
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
