vapour pressure
Type of information:
Adequacy of study:
key study
Study period:
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:
Attachments are provided in this endpoint study record.
Principles of method if other than guideline:
The result was obtained using an appropriate QSAR method (see attached QMRF and QPRF for details).
GLP compliance:
25 °C
Vapour pressure:
0.078 Pa
A vapour pressure 0.078 Pa at 25°C was obtained for the substance using an appropriate calculation method. The result is considered to be reliable.
