Description of key information

A vapour pressure of 0.001 Pa (25 °C) was calculated using Episuite (MPBPVP v1.43; Modified Grain method).

Key value for chemical safety assessment

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

Additional information

In accordance with column 2 of REACH Annex VII, the study does not need to be conducted if the melting point is between 200°C and 300°C, a limit value based on measurement or a recognised calculation method is sufficient. Although the method is not validated for organic salts, the calculated vapour pressure appears to be realistic based on the high melting temperature of the salt.
