Executive summary:

Modified Grain method was used to estimate the vapour pressure of the test chemical using MPBPVP v1.43 of EPI Suite. The estimated vapour pressure of test chemical at 25°C was evaluated to be 3.87E-12 mmHg (0.000000000516 Pa).

Description of key information

Based on the available data from authoritative and modelling databases, Modified Grain method was used to estimate the vapour pressure of the test chemical using MPBPVP v1.43 of EPI Suite. The estimated vapour pressure of test chemical was evaluated to be 3.87E-12 mmHg (0.000000000516 Pa) at 25°C.

Key value for chemical safety assessment

Vapour pressure:
0 Pa

Additional information

Based on the available data from authoritative and modelling databases, Modified Grain method was used to estimate the vapour pressure of the test chemical using MPBPVP v1.43 of EPI Suite. The estimated vapour pressure of test chemical was evaluated to be 3.87E-12 mmHg (0.000000000516 Pa) at 25°C.

In a supporting study from handbook, the vapour pressure of test chemical was estimated to be 4.46E-14 mmHg (0.00000000000594 Pa) at 25°C.
