Conclusions:

The present QSAR prediction was conducted with the EPISuite TM; MPBPWIN v1.43 software. The software uses three separate methods for vapour pressure prediction. However, the molecular weight is the main dose descriptor. The molecular weight of the test item lies within the range of molecular weights obtained from the training sets. Thus, the prediction is considered to be reliable. The vapour pressure of test substance was estimated to be 3.00E-10 Pa at 25°C.

Description of key information

- QSAR prediction, EPISuite / MPBPWIN v1.40 (2000). Vapour pressure was estimated to be 3.00E-10 Pa at 25°C.

Key value for chemical safety assessment

Vapour pressure:

0 Pa

at the temperature of:

25 °C

Additional information

According to a QSAR prediction permormed with EPISuite software and the MPBPWIN model (v 1.4; 2000) the vapour pressure was estimated to be  3.00E-10 Pa at 25°C.

The value of 3.00E-10 Pa is considered to be reliable since the substance lies within the QSAR prediction model validation with an extended data set of chemicals.
