- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- yes
- Remarks:
- maximum difference between the 24, 48 and 72 hours stirred samples was 17% due to a slightly higher result for the 24 hours stirred sample; this result however was considered to be within the spread of the analytical method

Results and discussion
Water solubility
- Water solubility:
- 11.1 mg/L
- Temp.:
- 20 °C
- pH:
- >= 4.8 - <= 4.9
- Details on results:
- - Preliminary test: the content of test substance dissolved in the water sample was 12 mg/L
- No test substance was detected in the pretreated samples from the blank water mixture
- Maximum difference between the 48 and 72 hours stirred samples was 10%
- Maximum difference between the 24, 48 and 72 hours stirred samples was 17% due to a slightly higher result for the 24 hours stirred sample. This result however was considered to be within the spread of the analytical method and not to be due to not having reached equilibrium. Based on this, it was decided to calculate water solubility as the average of all three values.

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The flask method was applied for the determination of the water solubility of the substance. The water solubility of the test substance at 20°C was 11.1 mg/L. The pH of the aqueous samples was 4.8 – 4.9.
