Reference
Endpoint:
vapour pressure
Type of information:
(Q)SAR
Adequacy of study:
supporting study
Study period:
2011
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
QSAR prediction
Principles of method if other than guideline:
The result was obtained using an appropriate QSAR method (see attached QMRF and QPRF for details).
Temp.:
25 °C
Vapour pressure:
0 Pa
Conclusions:
A vapour pressure of 5.3E-05 Pa at 25°C has been obtained for the test substance using an accepted calculation method. The result is considered reliable.
