Synthesis
2,5-Hexanedione has been prepared in several ways. A common method involves hydrolysis of 2,5-dimethylfuran, a glucose derived heterocycle.

Mechanism of Toxicity
Identification of 2,5-hexanedione as the major neurotoxic metabolite of n-hexane proceeded rapidly after its discovery as a urinary metabolite. 2,5-Hexanedione has been found to produce a polyneuropathy indistinguishable from n-hexane. 2,5-Hexanedione is many times more potent than n-hexane, the parent compound, in causing neurotoxicity in experimental animals. It appears that the neurotoxicity of 2,5-hexanedione resides in its γ-diketone structure since 2,3-, 2,4-hexanedione and 2,6-heptanedione are not neurotoxic, while 2,5-heptanedione and 3,6-octanedione and other γ-diketones are neurotoxic.

Chemical Properties   colourless to pale yellow liquid
Uses   It is the metabolite implicated in n-hexane neurotoxicity.
Definition
ChEBI: A diketone that is hexane substituted by oxo groups at positions 2 and 5. It is a toxic metabolite of hexane and of 2-hexanone

General Description   Clear colorless to amber liquid with a sweet aromatic odor.
Air & Water Reactions   Highly flammable. Water soluble.
Reactivity Profile   Acetonylacetone is incompatible with oxidizing agents. Acetonylacetone is also incompatible with strong bases and strong reducing agents.
Fire Hazard   Acetonylacetone is combustible.
Purification Methods   Purify it by dissolving in Et2O, stiring with K2CO3 (a quarter of the weight of dione), filtering, drying over anhydrous Na2SO4 (not CaCl2), filtering again, evaporating the filtrate and distilling it in a vacuum. It is then redistilled through a 30cm Vigreux column (p 11, oil bath temperature 150o). It is miscible with H2O and EtOH. The dioxime has m 137o (plates from *C6H6), the mono-oxime has b 130o/11mm, and the 2,4-dinitrophenylhydrazone has m 210-212o (red needles from EtOH). It forms complexes with many metals.
