4-Hydroxy-TEMPO Free Radical CAS 2226-96-2 Purity >99.0% (GC)

4-Hydroxy-TEMPO Free Radical (CAS: 2226-96-2) is a new alkenyl monomer polymerization inhibitor. It can be used as the replacer of hydroquinone and widely used in acrylic esters, methacrylic esters, vinyl acetate, acrylic acid, acrylonitrile, styrene, butadiene production. High efficient Polymerization inhibitor. It is a new kind of eco-friendly products because it can replace dihydroxybenzene And Intermediate material for synthesis of organic chemicials. It's performance is better than other polymerization inhibitors (such as phenolic, aromatic amine, aether, quinone, nitro-compound). It can also be used for vinyl chloride, unsaturated polyester and pesticide,the polymerization inhibition is better than phenols, aromatic amine, ethers, quinones, nitro compounds and other polymerization inhibitors. It can effectively prevent the production of olefin units and the autopolymerization in separation, refining, storage or transportation. It controls and adjusts the degree of polymerization of olefins and their derivatives in organic synthesis. Used as a spin marker for studying biological compounds and polymers; Used as an efficient catalyst in the oxidation of alcohols with bleach. It can replace benzenediol and is a new generation of environmentally friendly products.
