Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 pressure of the substance was determined to be 3.9*10 -5 hPa at 20 °C and 7.0*10 -5 hPa at 25 °C.
Key value for chemical safety assessment
- Vapour pressure:
- 0 hPa
- at the temperature of:
- 20 °C
Additional information
Two GLP studies were conducted. A study in accordance with the OECD Guideline for the Testing of Chemicals 104: "Vapour pressure" by effusion method, weight loss (made in 2004) determined the vapour pressure to be 3.9*10- 5 hPa at 20 °C and 7.0*10-5 hPa at 25 °C. A study equivalent or similar with the OECD Guideline for the Testing of Chemicals 104: "Vapour pressure" using the evaporation rate (made in 1994) determined the vapour pressure of the substance to be be 3.5*10-5 hPa at 20 °C and 6.5*10- 5 hPa at 25 °C.
The result of the more recent study made in 2004 was chosen as key value for the vapoure pressure.
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.
