Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test substance at 25 °C was calculated to 2.29E-14 Pa, using the MPBPVP v1.43 programme.
This value can not be entered in the field below.

Key value for chemical safety assessment

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

Additional information

According to REACH "The study does not need to be conducted if the melting point is above 300 °C.". The test substance decomposed starting at ca. 150 °C and did not melt until 400 °C. The calculated melting point is 333 °C. Therefore the estimation of the vapour pressure would not have to be performed.
