General Description |
2,2,6,6-Tetramethylpiperidinooxy (TEMPO) is a stable nitroxide radical widely used in catalysis, dynamic nuclear polarization (DNP) for NMR, and polymer chemistry. It exhibits high reactivity in alcohol oxidation and serves as a key component in biradical systems for enhancing DNP efficiency. TEMPO derivatives can be modified for recyclability in catalytic processes or incorporated into stimuli-responsive polymers, demonstrating versatility in both synthetic and materials applications. |
