Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 predicted vapour pressure = 3.29-09 mmHg, this value is considered as reliable. 

Key value for chemical safety assessment

Additional information

Assessment of the prediction

The prediction is "vapour pressure = 3.29-09 mmHg".

It is considered as reliable based on the following issues:

- similar compounds with known experimental value in the training set have been found;

- the similar molecules found in the training set and in the external test set have experimental values that agree with the predicted value;

- the accuracy of prediction for similar molecules found in the training set and in the external test set is quite good;

- all individual predictions obtained by means of different methods are quite similar.
