Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
<= 0.011 Pa at 20 °C
Key value for chemical safety assessment
Additional information
Calculation at 50 °C: <= 0.21 Pa.
The vapour pressure was determined with the use of Grain-Watson estimation as outlined in the OECD Guildeline 104. The calculation is based on the lowest possible boiling temperature, which in fact is probably a decomposition temperature. Therefore, they decompose before reaching their theoretical boiling points". Thus, the obtained value should be considered an upper limit of the vapour pressure and accepted for the risk assessment calculations in the sense of a "worst-case scenario". The same holds for the value calculated at 50 °C.
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.
