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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
2.3E-07 hPa (20 °C) (EU A.4, effusion method, regression curve)
Key value for chemical safety assessment
- Vapour pressure:
- 0 hPa
- at the temperature of:
- 20 °C
Additional information
The vapour pressure was extrapolated to be 2.3E-07 hPa at 20 °C. Actual vapour pressure of 1.5 x 10E-05 hPa could be measured at 63 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
