Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- (Q)SAR
- Adequacy of study:
- supporting 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 limited documentation / justification
- Justification for type of information:
- 1. SOFTWARE
EpiSuite v4.11, US EPA, 2012
2. MODEL (incl. version number)
MPBPWIN v1.43
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
O=C(CCS)OCCCCCCCCCCC(C)C
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
- Defined endpoint: vapour pressure
- Unambiguous algorithm:
MPBPWIN estimates vapor pressure (VP) by three separate methods: (1) the Antoine
method, (2) the modified Grain method, and (3) the Mackay method. All three use the
normal boiling point to estimate VP. Unless the user enters a boiling point on the data entry screen, MPBPWIN uses the estimated boiling point from the adapted Stein and Brown method. Equations can be found in the attached material.
- Defined domain of applicability:
Currently there is no universally accepted definition of model domain. However, users may wish to consider the possibility that property estimates are less accurate for compounds outside the Molecular Weight range of the training set compounds, and/or that have more instances of a given fragment than the maximum for all training set compounds. It is also possible that a compound may have a functional group(s) or other structural features not represented in the training set, and for which no fragment coefficient was developed. These points should be taken into consideration when interpreting model results.
- Appropriate measures of goodness-of-fit and robustness and predictivity:
The 3037 compound test set contains 1642 compounds with available experimental Boiling points and Melting points ... For this subset of compounds, the estimation accuracy statistics are (based on log VP):
number = 1642
r2 = 0.949
std deviation = 0.59
avg deviation = 0.32
These statistics clearly indicate that VP estimates are more accurate with experimental BP and MP data.
5. APPLICABILITY DOMAIN
- Descriptor domain: The components of the substance are within the molecular weight range of the training set compounds, and all fragments are represented in the training set. Thus, it is concluded, that the substance is within the applicability domain.
6. ADEQUACY OF THE RESULT
The QSAR prediction is valid and of good reliability. Thus, the result is adequate for chemical safety assessment. - Principles of method if other than guideline:
- Estimation of the vapour pressure by QSAR (EpiSuite v4.11, US EPA, 2012; MPBPWIN v1.43)
