Application

Chromium(III) acetylacetonate serves various significant purposes in scientific research and industrial applications. As a purple crystalline powder, it functions effectively as a catalyst in the oxidation of methacrylic esters by hydrogen peroxide and plays a role in Metal-Organic Chemical Vapor Deposition (MOCVD). Furthermore, Chromium(III) 2,4-pentanedionate is instrumental in reducing the detonation risk of nitromethane and is employed in NMR spectroscopy as a relaxation agent due to its solubility in nonpolar organic solvents and paramagnetism. This compound is also pivotal in modifying the surface properties of solid polyurethanes. It is an acidopentamminechromium (III) salt, produced by treating hydrous chromium(III) oxide with acetylacetone. Additionally, Chromium(III) acetylacetonate is valuable in developing redox systems for flow batteries and acts as a precursor for chromium nitride-based metallic coatings.
