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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
0.00347mmHg @ 25C (equivalent to 0.46Pa) - calculated
<0.01mmHg @ 25C (equivalent to <1.33Pa)
<0.013hPa at 20C
<2Pa at 20C (estimated from measured value of 0.076hPa at 40C)
~1Pa at 20C (estimated from Antoine constants determined at higher temperatures)
2.1hPa at 90C
Key value for chemical safety assessment
- Vapour pressure:
- 1 Pa
- at the temperature of:
- 298 K
Additional information
Reasonably consistent values are available from multiple sources, including values at different temperatures. Not all are absolute measurements - some are limit values and some are estimates based on measured data at higher temperatures. The key parameter is taken as a weight of evidence average across the available data and it can be concluded that the vapour pressure at ambient conditions is exceedingly low.
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.
