Description of key information

The melting point of 3-oxoglutaric acid was determined to be 138oC at atmospheric pressure of 990 hPa. The sample did not decompose or submlimate at the melting point. This value at 101 325 Pa is equivalent to 141.24oC

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
