- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 19 March 2015 - 05 September 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Version / remarks:
- (2008)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Version / remarks:
- (1995)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7840 (Water Solubility)
- Version / remarks:
- (1998)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- flask method
- Key result
- Water solubility:
- 62.1 g/L
- Temp.:
- 20 °C
- pH:
- 3.5 - 3.6
- Remarks on result:
- other: Mean of the concentrations analysed at t=48 h and t=72 h.
- Details on results:
- The concentration analysed after 24, 48 and 72 hours of stirring was 79.5 g/L, 63.8 g/L and 60.4 g/L , resp. The maximum difference (MD) is >15% in this case (28.1%). Based on this, the water solubility of the test substance was given as the mean value of the 48- and 72-hour measurements, as the MD is ≤ 15% in this case (5.5%). No test substance was detected in the pretreated sample from the blank water mixture.
- Conclusions:
- Interpretation of results: very soluble (> 10000 mg/L)
In a GLP-compliant study in accordance with EC A.6, OECD 105 and OPPTS 830.7840 using the flask method, the water solubility of the substance at 20°C has been determined as 62.1 g/L. The pH of the saturated solution was 3.5-3.6.
