Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance was predicted to have vapour pressure of 0.115 mm Hg at 25 °C. After conversion, the key value is 15.3 Pa at 25 °C.

Key value for chemical safety assessment

Vapour pressure:
15.3 Pa
at the temperature of:
25 °C

Additional information

The value(0.115 mm Hg at 25 °C) used for key study is obtained from reliable QSAR software which is developped by U.S.  Environmental Protection Agency. The key value is consistent with the extrapolated data(0.1 mm Hg at 25 °C) in Perry's Chemical Engineers' Handbook. However, this value is from the data of isomers mixture, then it just can be used as supporting data. Besides, there are another two supporting data whose reliability are not high enough as key study.
