Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
