Materials and methods
Test guidelineopen allclose all
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:

- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- yes
- Remarks:
- see 'Principles of method if other than guideline'
- Principles of method if other than guideline:
- In an agitated and filtrated mixture of the test item, a concentration below 10 mg/L was measured during validation. Therefore, the preliminary study was not performed. Solubility could be limited as lying below 10 mg/L and the main study was conducted using the column elution method.
- GLP compliance:
- no
- Type of method:
- column elution method

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results: slightly soluble (0.1-100 mg/L)
The water solubility of the test substance has been determined to be 0.333 mg/L (pH = 6; temperature ~ 23 °C) and therefore the substance is considered to be slightly soluble in water.
