Description of 2,2,6,6-Tetramethylpiperidinooxy
(2,2,6,6-Tetramethylpiperidin-1-yl)oxyl or (2,2,6,6-tetramethylpiperidin-1-yl)oxidanyl, commonly known as TEMPO, is a chemical compound with the formula (CH2)3(CMe2)2NO. This heterocyclic compound is a red-orange, sublimable solid. As a stable radical, it has applications in chemistry and biochemistry. TEMPO was discovered by Lebedev and Kazarnowskii in 1960. It is prepared by oxidation of 2,2,6,6-tetramethylpiperidine. TEMPO is widely used as a radical marker, as a structural probe for biological systems in conjunction with electron spin resonance spectroscopy, as a reagent in organic synthesis, and as a mediator in controlled radical polymerization. The stability of this radical is attributed to the resonance provided by non-bonding electrons on the nitrogen atom, which form a 2c3e (half-) bond between nitrogen and oxygen, and hyperconjugative ability. Additional stability arises from the steric protection provided by the four methyl groups adjacent to the nitroxyl group; however, the methyl groups prevent a double bond occurring between either carbon adjacent to nitrogen. The stability of the radical is also indicated by the weakness of the O–H bond in the hydrogenated derivative TEMPO–H. With an O–H bond dissociation energy of about 70kcal/mol, this bond is about 30% weaker than a typical O–H bond.

What is 2,2,6,6-Tetramethylpiperidinooxy?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 2,2,6,6-Tetramethylpiperidinooxy which has developed particularly rapidly in recent years. Do you know about 2,2,6,6-Tetramethylpiperidinooxy?
The official answer:2,2,6,6-Tetramethylpiperidine oxide, an organic chemical substance, molecular formula: C9H18NO.
What’s the application of 2,2,6,6-Tetramethylpiperidinooxy?
TEMPO has wider applications in chemistry, biology, food industry, agriculture, and other fields. It has the functions of trapping free radicals, bursting single-linear oxygen, and selective oxidation. In polymer chemistry, it is used as a radical trapping agent, polymerization inhibitor, anti-aging agent, thermal degradation inhibitor, and light and heat stabilizer, and it can also combine with reactive chain radicals to form covalent dormant species. The covalent dormant species can be cleaved into chain radicals and grow again. TEMPO/NaClO/NaBr is a recyclable oxidation system in which the real oxidant is the NaClO oxidation of TEMPO to produce the intermediate N- oxoammonium ion, the primary hydroxyl nucleophile attacks the ion, the hydroxyl group is oxidized to a carboxyl group, and the ion is converted to hydroxylamine, which is then oxidized to N-oxoammonium ion by the co-oxidant, and so on. Many other oxidation systems are containing TEMPO.
