Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 2017 OCTOBER 01
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:

- Justification for type of information:
- Estimated data are obtained from a reliable (Q)SAR program developed and validated by the United States Environmental Protection Agency (U.S. EPA). This program is included in the OECD (Q)SAR Toolbox for use in filling REACH data gaps.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: US EPA EPI-Suite MPBPVP v1.43
- GLP compliance:
- no
- Type of method:
- other:
- Remarks:
- Estimated data are obtained from a reliable (Q)SAR program developed and validated by the United States Environmental Protection Agency (U.S. EPA). This program is included in the OECD (Q)SAR Toolbox for use in filling REACH data gaps.
