Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The vapour pressure of the substance at 20°C was determined to be 7.5E-05 Pa.
The vapour pressure of the substance at 25°C was determined to be 1.1E-04 Pa.
Executive summary:

The vapour pressure of the substance was determined using the isothermal thermogravimetric effusion method in a GLP study according to EC A.4, OECD 104 and OPPTS 830.7950. The vapour pressure regression curve was constructed from duplicate measurements at 210°C, 220°C and 230°C. The vapour pressure of the substance at 20°C and 25°C was calculated to be 7.5E-05 Pa and 1.1E-04 Pa, resp.
