2,2,6,6-Tetramethylpiperidinooxy/TEMPO with Cas 2564-83-2
What is 2,2,6,6-Tetramethylpiperidinooxy/TEMPO?
2,2,6,6-Tetramethylpiperidinooxy, abbreviated as TEMPO, is a nitrogen oxygen radical of the pyridine family. TEMPO is an orange red crystal or liquid that is easily sublimated and soluble in solvents such as water, ethanol, and benzene. It has the function of capturing free radicals and quenching singlet oxygen, and is a very effective oxidation catalyst that can oxidize primary alcohols to aldehydes and secondary alcohols to ketones.
Due to the steric hindrance effect of the four methyl groups, TEMPO is a highly effective oxidation catalyst that is relatively stable to light and heat, capable of oxidizing primary and secondary alcohols into the desired carbonyl compounds. It has the characteristics of high yield, good selectivity, good stability, and recyclability.
