- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- according to guideline
- Guideline:
- other:
- Version / remarks:
- method described in the External method EM/00408/01 from Competence Center Analytics
- Deviations:
- no
- Principles of method if other than guideline:
- The water solubility of substances with an expected high solubility is normally determined according to flask method described in OECD Guideline for the Testing of Chemicals 105.
To apply this method, the preparation of a saturated solution of test item in water is required. Since this is not possible for this test item, a homemade method described in the External method EM/00408/01 from Competence Center Analytics. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: homemade method described in the External method EM/00408/01 from Competence Center Analytics
- Key result
- Water solubility:
- 1 000 g/L
- Conc. based on:
- test mat.
- Temp.:
- 23 °C
- pH:
- 5.4
- Details on results:
- The test item is miscible with water at room temperature (T = 23 °C) and at T = 20.0 °C ± 0.5 °C in any ratio.
- Conclusions:
- The test item is miscible with water at room temperature (T = 23 °C) and at T = 20.0 °C ± 0.5 °C in any ratio.
