[Chemical Properties]

white to off-white powder
[Physical properties]

Acetonedicarboxylic acid forms colorless crystals that are readily soluble in water and ethanol, and sparingly soluble in trichloromethane and diethyl ether. It melts with decomposition at 138 ℃.
[Uses]

β-Ketoglutaric Acid is used in the synthesis of benzodiazepine derivatives. Also used in the synthesis of orally available hepatitis C virus polymerase inhibitors.
[Definition]

ChEBI: 3-Oxoglutaric acid is an oxo carboxylic acid.
[Production Methods]

Acetonedicarboxylic acid is produced from citric acid [77-92-9] by many industrial processes that differ only slightly. Citric acid is treated with oleum and reacts to yield acetonedicarboxylic acid via decarbonylation and dehydration.
Other possible production methods include reaction of acetone with carbon dioxide, oxidation of citric acid with chlorosulfuric acid, or reaction of ketene with phosgene.
[Flammability and Explosibility]

Nonflammable
[storage]

Store at -20°C,unstable in solution, ready to use.
[Purification Methods]

Crystallise it from ethyl acetate and store it over P2O5. It decarboxylates in hot water. [Beilstein 3 IV 1816.]
