Chromium(III) 2,4-pentanedionate, 97%, Thermo Scientific Chemicals

Description

Catalyst in the oxidation of methacrylic esters by hydrogen peroxide, MOCVD

Catalyst in the oxidation of methacrylic esters by hydrogen peroxide, MOCVDChromium(III) 2,4-pentanedionate is used in the reduction of detonation of nitromethane. It is also used in NMR spectroscopy as a relaxation agent due to its solubility in nonpolar organic solvents and its paramagnetism. Further, it is involved in the modification of the surface properties of solid polyurethanes.
