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 a building blocks in organic chemistry, particuarly in the synthesis of hetrocyclic rings[3] and in the Weiss–Cook reaction.

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]
