- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7840 (Water Solubility)
- GLP compliance:

- Type of method:
- flask method
- Water solubility:
- 712 g/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- pH:
- 5.2
- Key result
- Water solubility:
- 718 g/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- pH:
- 7.2
- Water solubility:
- 713 g/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- pH:
- 9.2
- Details on results:
- The water solubility of pure substance at 20 °C is 712 g /L solution, 718 g/L and 713 g/L, in water buffered at pH 5.2, pH 7.2 and pH 9.2 respectively. Since the substance cation does not possess any functional groups that are likely to protonate or deprotonate in the pH range 0 - 14 its water solubility is not affected by pH, any slight difference being accounted for by method error. The water solubility in purified wrater will therefore also be in the same range.
- Conclusions:
- At 20 °C the water solubility of the test substance ranged from 712 to 718 g/L between pH 5.2 and 9.2.
- Executive summary:
The water solubility of the test substance has been determined using the flask method in accordance with OECD TG 105, the EU method A. 6. and the EPA test guideline OPPTS 830.7840 and in compliance with GLP. The solubility of the pure test substance in water at 20 °C was found 712 g/L at pH 5.2, 718 g/L at pH 7.2 and 713 g/L at pH 9.2.
