4-Hydroxy-2,2,6,6-tetramethyl-piperidinooxy CAS# 2226-96-2

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.
