Reference
Endpoint:
vapour pressure
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, with adequate and reliable documentation / justification
Remarks:
The scientific validity of the (Q)SAR model has been established in accordance with the OECD Principles for (Q)SAR Model Validation
Justification for type of information:
QSAR prediction
Qualifier:
according to guideline
Guideline:
other: Data generated using EPI Suite v.4 (MPBPVP V. 143)
Principles of method if other than guideline:
Input Values
BP: 208.95 C
MP: -24.55 C
GLP compliance:
no
Temp.:
25 °C
Vapour pressure:
3.91 Pa
Remarks on result:
other: Temperature is assumed to be 25°C, 2.92E-2 mm Hg
Conclusions:
Vapour pressure was calculated to be 3.91 Pa (2.92E-2 mm Hg) at 25 °C using EPI Suite v.4.
Executive summary:

Vapour pressure was calculated to be 3.91 (2.92E-2 mm Hg) Pa at 25 °C using EPI Suite v.4.
