Reference
Endpoint:
Henry's law constant
Type of information:
(Q)SAR
Adequacy of study:
key study
Study period:
25 MAY 2022
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
Justification for type of information:
1. SOFTWARE
OECD QSAR toolbox v 4.5

2. MODEL (incl. version number)
HENRYWIN v 3.21

4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
Please refer to the QMRF attached under 'Attached justification'.

5. APPLICABILITY DOMAIN
Please refer to the QPRF attached under 'Attached justification'.
Guideline:
other: REACH guidance on QSARs Chapter R.6
Version / remarks:
May 2008
Principles of method if other than guideline:
Software tool(s) used including version: OECD QSAR toolbox v4.5, EPI Suite v4.11
- Model(s) used: HENRYWIN v3.21
- Model description: see field 'Attached justification'
- Justification of QSAR prediction: see field 'Justification for type of information', 'Attached justification'
Specific details on test material used for the study:
CP(=O)(Oc2ccccc2)Oc1ccccc1
H:
0.017 Pa m³/mol
Temp.:
25 °C
Remarks on result:
other: Bond Method estimation
Conclusions:
The Henry´s Law Constant value using bond method estimation by US-EPA software HENRYWIN v3.21 gives 0.0173 Pa m^3/mol at 25 °C.
Executive summary:

The Henry´s Law Constant value using bond method estimation by US-EPA software HENRYWIN v3.21 gives 0.0173 Pa m3/mol at 25 °C. The predicted substance falls into the MW range of the training set compounds. Thus, it is considered to be in the applicability domain of this model.

Description of key information

Calculation with HENRYWIN v3.21 (EPIWIN software by US-EPA): 1.73E-2 Pa*m³/mol

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0.017

Additional information

The Henry´s Law Constant value using bond method estimation by US-EPA software HENRYWIN v3.21 gives 0.0173 Pa m3/mol at 25 °C. The predicted substance falls into the MW range of the training set compounds. Thus, it is considered to be in the applicability domain of this model.
