Vapour pressure
Administrative data
- 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 and falling into its applicability domain, with adequate and reliable documentation / justification
- Remarks:
- The EPISuite model is considered to be a well-developed model. The chemistry appears to be within the domains of the model.
- Justification for type of information:
- Modelled data using acceptable model.
