Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 by the static method to be 68 Pa at 25°C.
Key value for chemical safety assessment
- Vapour pressure:
- 68 Pa
- at the temperature of:
- 25 °C
Additional information
A vapour pressure determination was performed by HLS (2008, Report No.: IDK0104). The vapour pressure was determined according to OECD Method 104 and EU Method A4 and was considered to be reliable. T13-h was found to have a vapour pressure 68 Pa at 25°C.
