Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 determined as 3.17 x 10-4 ± 7.02 x 10-6 Pa at 20 degrees Centigrade

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

In a GLP, OECD guideline 104 study, spinning rotor gauge (SRG) measurement was initiated with a determination of the offset value, system background pressure and out-gassing rate in the absence of sample. The vacuum system and SRG were then exposed to the test substance until a steady state pressure was obtained. The sample and SRG were then isolated from the vacuum pumps and the pressure increase was monitored by the SRG at 30-second intervals. A linear regression was obtained for pressure increase as a function of time.
