Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EU method A.4. (92/69/EEC): Calculation, MPBPWIN Version 1.40 (modified Grain method)

Key value for chemical safety assessment

Vapour pressure:
0.001 Pa
at the temperature of:
298 K

Additional information

Experimental determination of the vapour pressure of the active substance is not applicable due to the ionic structure and deliberation of crystal water at reduced pressure.

From the result of the model calculation (<1Eāˆ’05 Pa) it can be concluded that no measurement is required because the calculated value is far below the detection limit of the available methods.
