Description of 4-Hydroxy-2,2,6,6-tetramethyl-piperidinooxy
4-Hydroxy-TEMPO or TEMPOL, formally 4-hydroxy-2,2,6,6-tetramethylpiperidin-1-oxyl, is a heterocyclic compound. Like the related TEMPO, it is used as a catalyst and chemical oxidant by virtue of being a stable radical. Its major appeal over TEMPO is that is less expensive, being produced from triacetone amine, which is itself made via the condensation of acetone and ammonia. This makes it economically viable on an industrial scale.
In biochemical research, it has been investigated as an agent for limiting reactive oxygen species. It catalyzes the disproportionation of superoxide, facilitates hydrogen peroxide metabolism, and inhibits Fenton chemistry.

What is 4-Hydroxy-2,2,6,6-tetramethyl-piperidinooxy ?
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 4-Hydroxy-2,2,6,6-tetramethyl-piperidinooxy which has developed particularly rapidly in recent years. Do you know about 4-Hydroxy-2,2,6,6-tetramethyl-piperidinooxy?
The official answer：A polymerization inhibitor is an industrial additive that is usually used to prevent polymerization from taking place. The polymerization is terminated by the reaction of the inhibitor molecule with the chain radicals, forming non-radical substances or less reactive radicals that cannot be initiated.
What’s the application of 4-Hydroxy-2,2,6,6-tetramethyl-piperidinooxy?
1.Used as a spin marker for the study of biological compounds and polymers; spin labeling reagent for the identification of antagonist and agonist binding sites for the NK1 receptor and the determination of reactive oxygen species production in the myocardium by electron spin resonance spectroscopy; TEMPOL protects cells overexpressing ChemicalbookCYP2E1 from toxic damage by arachidonic acid; used as a fluorine-labeled TEMPO derivative that can be derived from the derivatization of TEMPO propargyl ether and subsequent “click” reactions with fluorides to prepare fluorine-labeled TEMPO derivatives; used as an efficient catalyst in the oxidation of alcohols with bleach.
2.It has better polymerization inhibiting effect on acrylates, methacrylates, acrylic acid, acrylonitrile, styrene, and butadiene. Its polymerization inhibiting performance is better than phenols, aromatic amines, ethers, quinones and nitro compounds, and other inhibitors.
3.To prevent self-polymerization of olefin monomers during production, separation, refining, storage or transportation, and to control and regulate the degree of polymerization of olefins and their derivatives.
