Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient - Shake Flask Method)
- GLP compliance:
- not specified

Applicant's summary and conclusion
- Conclusions:
- Both shake flask test and derivation of the logPow from the measured solubility in n-octanol (visual assessment), and measured water solubility methods have been applied to measure the partition coefficient. The log Pow was determined from the measured ratio of solubilty in n-octanol and in water at was determined at >6.18.
- Executive summary:
Both shake flask test and derivation of the logPow from the measured solubility in n-octanol (visual assessment), and measured water solubility mthods have been applied to measure the partition coefficient. The log Pow was determined from the measured ratio of solubilty in n-octanol and in water at was determined at >6.18.
