Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Vapour pressure: 104 hPa at 20°C

Key value for chemical safety assessment

Vapour pressure:
104 hPa
at the temperature of:
20 °C

Additional information

Vapour pressure values of 104 hPa at 20°C and 126 hPa at 25°C were reported for the registered substance in two separate handbooks or collections of reliable data which have been subject to peer-review. The results are used as weight of evidence.
