Applicant's summary and conclusion

Conclusions:

Interpretation of results (migrated information): moderately soluble (100-1000 mg/L)
The water solubility of the test item is 164 mg/L at 20°C determiend according to OECD 105.

Executive summary:

The water solubility of the test item was determined accordding to OECD guideline 105 with flask method. Solubities were checked after 1, 2 rsp. 3 days equilibration time, resukting in a mean water solubility of 164 mg/L at 20°C.
