Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key result
25 °C
Vapour pressure:
5 405 hPa

Description of key information

The vapour pressure of the substance was determined to be 5405 hPa in the NAS review publication.

Key value for chemical safety assessment

Vapour pressure:
5 405 hPa
at the temperature of:
25 °C

Additional information

A study to determine the vapour pressure was considered technically not feasible as the boiling point of the substance is below 30 °C. The estimated vapour pressure would be above the limit of measurement. Therefore, data from a scientific publication was used as key value.
