Description of key information

The melting point of dimethyl sulphate is -32 °C at 1013 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-32 °C

Additional information

A literature review was conducted. In a weight of evidence approach the literature values were evaluated. REAXYS reports the melting point to be between -32.16 °C and -26.8 °C at 1013.25 hPa. HSDB reports the melting point to be -27 °C at 1013.25 hPa.

The GESTIS database reports the melting point to be -32 °C at 1013.25 hPa and IPCS International Programme on Chemical Safety report the melting point to be -32 °C at 1013,25 hPa. Four independent literature sources report the melting point in the same range. Thus, a melting point of -32 °C at 1013,25 hPa from the IPCS International Programme on Chemical Safety which is a peer reviewed data base was chosen as key value.
