Applications

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.

Notes

Incompatible with strong oxidizing agents.
