Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

25 °C

Additional information

The vapour pressure of the substance is derived from a weight-of-evidence approach of two experimental studies and two secondary sources. The values derived from these sources fit together and differ only in a minor range. SRC (1985) as a peer reviewed database is considered as the most reliable source and is therefore chosen as key value for the chemical safety assessment since the experimental studies are determined at higher temperatures and the values are extrapolated. Nevertheless, the values harmonize well together and support the key value.
