Acetonedicarboxylic acid, 3-oxoglutaric acid or β-ketoglutaric acid is a simple dicarboxylic acid.


It is commercially available but may also be prepared by decarbonylation of citric acid in fuming sulfuric acid:[2]

Acetonedicarboxylic acid and its derivatives are primarily used as building blocks in organic chemistry, particularly in the synthesis of heterocyclic rings[3] and in the Weiss–Cook reaction.

Acetonedicarboxylic acid is well-known to be used in the Robinson tropinone synthesis.

Acetonedicarboxylic acid also finds use in the synthesis of Timcodar & dezaguanine (3-deazaguanine, 3-DG).

Diethyl 1,3-acetonedicarboxylate saw use in the synthesis of Zomepirac.

The presence of β-ketoglutaric acid in human urine can be used as a diagnostic test for the overgrowth of harmful gut flora such as Candida albicans.[4]
