Appearance: orange crystal
Content: ≥99.0%
Melting point: 69-73℃
Solubility: soluble in organic solvents such as ethanol and benzene, and soluble in water.
Ash content: ≤0.1%
Storage method: It is easy to absorb moisture and needs to be stored under airtight and dry conditions to prevent high temperature. The packaging should be kept intact and stored in a ventilated and tidy warehouse. Avoid storage with other acid chemicals.
Chemical properties: soluble in organic solvents such as ethanol and benzene, and soluble in water.
Uses: This product has a good inhibitory effect on acrylic esters, methacrylic esters, acrylic acid, acrylonitrile, styrene, butadiene. Its polymerization inhibition performance is better than that of phenols, aromatic amines, ethers, quinones and nitro compounds.
Uses: Used as a spin marker for the study of biological compounds and polymers; spin labeling reagents, used to identify the antagonist and agonist binding sites of NK1 by the Chemicalbook body, and can also be used for electron spin resonance spectroscopy to determine the myocardium TEMPOL can protect cells overexpressing CYP2E1 from the toxic damage of arachidonic acid; used as a fluorine-labeled product by derivatizing TEMPO propynyl ether and the subsequent "click" reaction with fluoroazide TEMPO derivative; used as a high-efficiency catalyst in the oxidation of alcohol with bleaching agent.
Uses: Used to prevent self-polymerization of olefin monomers during production, separation, refining, storage or transportation, and to control and adjust the degree of polymerization of olefins and their derivatives.
