Descripción general
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.
Aplicación
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.
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
