Application
Chromium(III) acetylacetonate can be used as:
- A precursor for the synthesis of chromium oxide (Cr₂O₃) nanoparticles, which are utilized in magnetic, catalytic, and electrochemical devices
- A molecular precursor in chemical vapor deposition (CVD) and sol-gel processes to fabricate chromium-containing thin films for electrochromic and energy storage applications
- A catalyst or catalyst precursor in selective oxidation and polymerization reactions, enabling efficient and sustainable organic transformations
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.

Current precious-metal-containing anticancer agents are mostly chelated with N-containing ligands and function by interacting with DNA. In the present study, Pd(acac)2, a Pd(II) complex containing four O-donor ligands, has been evaluated as an active anticancer agent. Pd(acac)2 showed no interaction

Nearly monodisperse lanthanide-doped magnetite nanoparticles were obtained by thermally decomposing a mixture of Fe(acac)(3) and Ln(acac)(3) (acac = acetylacetonate; Ln = Sm, Eu, Gd) in the presence of passivating surfactants. Magnetic studies revealed room-temperature ferromagnetic behaviors of these doped nanoparticles
