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 (Q)SAR model, with limited documentation / justification, but validity of model and reliability of prediction considered adequate based on a generally acknowledged source
Justification for type of information:
See EpiSuite report (attached).
Qualifier:
no guideline required
Principles of method if other than guideline:
EPI (Estimation Programs Interface) Suite estimates a range of physicochemical properties, environmental fate parameters and ecotoxicity. It has been developed by the US EPA in collaboration with Syracuse Research Corporation (SRC) and is used widely by governmental and industry organisations to support the assessment of new and existing industrial chemicals.
GLP compliance:
no
Temp.:
25 °C
Vapour pressure:
0 Pa
Remarks on result:
other: QSAR prediction
Conclusions:
EpiSuite (MPBPWIN v1.43) estimates vapour pressure as 2.79 x 10E-09 Pa at 25 °C (modified Grain Method).
Executive summary:

EpiSuite (MPBPWIN v1.43) estimates vapour pressure as 2.79 x 10E-09 Pa at 25°C (modified Grain Method).
