General description
Acetylacetone (2,4-pentanedione) is an organic compound containing two carbonyl groups and one active methylene group. It is mainly used as an intermediate in the synthesis of various chemical derivatives. It can also be used as a modifier for polyolefins, corrosion inhibitors, and labeling of radiotracers.
Application
Acetylacetone can be used as:
- A multifunctional ligand in the synthesis and feasible functionalization of gold nanoparticles (AuNPs).
- A reactant to synthesize 9,10-dihydroacridines by reacting with methyl acetoacetate and Morita-Baylis-Hillman acetates.
- A reagent in the synthesis of ZrO2(zirconium dioxide) via hydrolysis of Zr(OC3H7n)4. Acetylacetone controls the hydrolysis and condensation rates of alkoxides and thus, the nucleation and growth rates of oxides.

Bacteria have developed a cell-to-cell communication system, termed quorum sensing (QS), which allows for the population-dependent coordination of their behavior via the exchange of chemical signals. Autoinducer-2 (AI-2), a class of QS signals derived from 4,5-dihydroxy-2,3-pentandione (DPD), has been revealed

A series of high-spin iron(II) β-diketonato complexes have been prepared and characterized with the intent of modeling the substrate-bound form of the enzyme acetylacetone dioxygenase (Dke1). The Dke1 active site features an Fe(II) center coordinated by three histidine residues in
