Chemical Properties
solid
Uses
Part of furannulation strategy for the synthesis of naturally occurring fused 3-methylfurans.1
Uses
Used in the synthesis of fused 3-methylfurans via furannulation.
Uses
Reagent used in synthesis of fused 3-methylfuransDimedone is used in organic chemistry to identify the presence of aldehyde group. It is also used as a catalyst in the formation of transition-metal complexes. Further, it is also employed in colorimetry, crystallography, luminescence and spectrophotometric analysis. In addition to this, it is used in the synthesis of naturally occurring fused 3-methylfurans.
Uses
A mentha compound showing antimicrobial properties against common bacteria in the food industry such as E.coli and P.aeruginosa as well as strains of yeast.

General Description
5,5-dimethyl-1,3-cyclohexanedione (Dimedone) is basically a highly sensitive and very specific reagent used for the determination of aldehydes. It is highly advantageous as it is environment friendly, give high yields and is a simple workup procedure.
Purification Methods
Crystallise dimedone from acetone (ca 8mL/g), water or aqueous EtOH. Dry it in air. [Schneider & Todd Org Synth Coll Vol II 200 1943, Beilstein 7 H 559, 7 IV 1999.]
