Description of key information

The vapour presure of dimthyl sulphate is 0.65 hPa at 20 °C.

Key value for chemical safety assessment

Vapour pressure:
0.65 hPa
at the temperature of:
20 °C

Additional information

A literature review was conducted. In a weight of evidence approach the literature values were evaluated. The

IPCS International Programme on Chemical Safety and Knovel - A poroperties database reports the vapour pressure to be 0.65 hPa at 20 °C. The GESTIS Substance database reports the vapour pressure to be 0.35 hPa at 20 °C and the HSDB reports the vapour pressure to be 0,903 hPa at 25°C. Four independent literature sources report the vapour pressure in the same range. Thus, a vapour pressure of 0.65 hPa which represent the 20°C value and has a peer reviewed source was chosen as key value.
