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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Reference
Validity criteria for the measurement of the vapour pressure:
| Target condition according to guideline: | Actual condition according to the study: | Validity criteria met: |
| At least two vapour pressure and temperature values - and preferably three or more – are required in the range 0 to 50 °C (or 120 to 150 °C). | 10 vapour pressure and temperature values were stated in the range of 107.2 - 193.2 °C (dynamic method) and 7.6 - 14.2 °C (effusion method). | Yes |
| A log p versus 1 /T curve should be stated. | The vapour pressure (logarithmic scale) as a function of the inverse temperature 1/T (T in Kelvin) was stated. | Yes |
| An estimate of the vapour pressure at 20 or 25 °C should be stated. | Calculated vapour pressure values that were extrapolated were stated for 20 and 25 °C. | Yes |
Description of key information
The calculated vapour pressure values are extrapolated to 2.8E-4 hPa at 20°C.
Key value for chemical safety assessment
- Vapour pressure:

Additional information
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.
