Results and discussion
Partition coefficient
- Key result
- Type:
- log Pow
- Partition coefficient:
- > 6
- Temp.:
- 25 °C
- pH:
- ca. 7
- Details on results:
- The 100 mg of the test item, RM1004951 dissolved completely in 0.1 mL n-octanol, the solubility was therefore >500 g/L
The water solubility was approximately 0.0001 g/L. Therefore the Pow value is >5000000 and the equivalent log10Pow value can be said to be >6.
Applicant's summary and conclusion
- Conclusions:
- The substance was found to have log10Pow value of >6.
- Executive summary:
The substance was found to have log10Pow value of >6.
