Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Notified substance: <0.013Pa at 20C
Surrogate substance: 1.6Pa at 20C

Key value for chemical safety assessment

Vapour pressure:
0.01 Pa
at the temperature of:
293 K

Additional information

Data on the notified substance indicates that the vapour pressure at 20C is very low. Data from a full study report on a similar but lower molecular weight substance provided supporting evidence that this low vapour pressure data is valid.
