Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 vapour pressure of the substance was measured at 3 different temperatures (24.14, 29.90, 36.05°C) and an evaluation of the vapour pressure at 25°C was calculated using these points.

Key value for chemical safety assessment

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