Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient)
- Principles of method if other than guideline:
- The solubility of the substance in n-octanol and water was separately determined then the Pow calculated as n-octanol solubility/water solubility.
- GLP compliance:
- no
- Type of method:
- other: Ratio of measured solubilities
- Partition coefficient type:
- octanol-water
Test material

- Cas Number:
- 84961-74-0

Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- > 0.51
- Temp.:
- 20 °C
- Remarks on result:
- other: Determined by ratio of solubilities in n-octanol and water
- Details on results:
- The solubility in n-octanol was determined to be >750 g/L at 20 degC. The water solubility was determined to be >230 g/L. Therefore the Pow is calcuated as >750/230 = > 3.26. Therefore the log Pow is >0.51
Applicant's summary and conclusion
- Conclusions:
- The substance has a log Pow of >0.51
