General description
Chromium(III) acetylacetonate (Cr(acac)₃) is a high-purity (≥97%) coordination complex that appears as a purple to very dark purple powder or in chunk form. It is a stable, air-insensitive compound, soluble in non-polar organic solvents. Its high thermal stability and well-defined molecular structure make it an excellent precursor for synthesizing advanced materials. Cr(acac)₃ is especially valued for applications in catalysis, thin film deposition, and as a molecular probe in spectroscopic studies.
