What Is 2,2,6,6-Tetramethylpiperidinooxy
2,2,6,6-Tetramethylpiperidinooxy/TEMPO, is a kind of piperidine nitrogen oxide radical. TEMPO is orange or red crystal or liquid that is easy to sublimate and soluble in water, ethanol, benzene and other solvents. It has the function of capturing free radicals and quenching singlet oxygen, and is a very effective oxidation catalyst, which can oxidize primary alcohols to aldehydes and secondary alcohols to ketones.
