Materials and methods
Test guidelineopen allclose all
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient)
- Deviations:
- no
- Principles of method if other than guideline:
- Estimation method:
The solubility of the test substance in n-octanol and in water is determined. The quotient of the n-octanol solubility and the water solubility is an
estimation of the Pow· The estimation method can be applied if the shake flask method and HPLC method are not applicable. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: estimation method
- Partition coefficient type:
- octanol-water

- Partition coefficient:
- 1.55
- Temp.:
- 19.9 °C
- Remarks on result:
- other: The pH value is not separately mentioned in the test report. Nevertheless, a pH value of 6.8 is reported from the water solubility study at 0.451 g/L after 72 h stirring time at 19.9 °C ± 0.5 °C. Both tests results are reported in the same test report.
