Details on results:
The analysed concentration of the stock solution was 0.113 g/L. Based on this the nominal quantity of the test item in the test samples was 0.227 mg. The recoveries were determined according to this value.
The log Pow values were within the criterion range of ± 0.3 log units. The Pow and log Pow of the test item are given as the mean value of all measurements.
No test item was detected in the pre-treated samples from the blank mixture.

Applicant's summary and conclusion

Conclusions:
The shake flask method at neutral pH was applied for the determination of the partition coefficient (Pow) of CH02241.
The Pow value of the test item was 2.7 * 10^-1. It corresponds with a log Pow value of -0.6.
