2,2,6,6-Tetramethylpiperidinooxy CAS NO.2564-83-2

Tetramethylpiperidine oxide, abbreviated as TEMPO, is a nitrogen oxide radical of the piperidine class. It is an orange red easily sublimated crystal or liquid, soluble in solvents such as water, ethanol, and benzene, toxic, corrosive, and can be absorbed through the skin with strong irritation. 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. It has the advantages of high yield, good selectivity, good stability, and recyclability.

TEMPO was first prepared by Lebedev and Kazarnowskii in 1960 and has been widely used in fields such as chemistry, biology, food industry, and agriculture. TEMPO is a very effective oxidation catalyst that can oxidize primary and secondary alcohols into the required carbonyl compounds. It has the characteristics of high yield, good selectivity, good stability, and recyclability.

Storage conditions: 2-8 ° C

Stability: Stable. Stay away from strong acids and oxidants. Need to refrigerate.

It has functions such as capturing free radicals, quenching singlet oxygen, and selective oxidation. It is used as free radical trapping agent, polymerization inhibitor, anti-aging agent, thermal degradation inhibitor, light and heat stabilizer in polymer chemistry, and can also combine with active chain free radicals to form covalent dormant species. Covalent dormant species can split into chain free radicals and grow again. Used as various alcohols and polyols in organic synthesis
