Acetonedicarboxylic acid and its derivatives are primarily used as a building blocks in organic chemistry, particularly in the synthesis of hetrocyclic rings 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.
