key study
Study period:
2006
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.6 (Water Solubility)
Qualifier:
according to
Guideline:
OECD Guideline 105 (Water Solubility)
GLP compliance:
yes (incl. certificate)

RS-Freetext:
solubility in distilled water at different temperatures:
39.7 mg/L (8.4 °C), 32.8 mg/L (20.4 °C), 27.5 mg/L (33.4 °C)

solubility in water at neutral pH and different temperatures:
36.1 mg/L (8.4 °C), 28.9 mg(L (20.4 °C), 23.1 mg/L (33.4 °C)

solubility at different pH-values and 20 °C:
30.7 mg/L (pH 4.06), 32.8 mg/L (pH 6.12), 28.9 mg/L (pH 7.01), 30.5 mg/L  (pH 8.86)

The water solubility is slightly dependent on temperature and not  dependent on pH.

Conclusions:
Interpretation of results: slightly soluble (0.1-100 mg/L)
The water solubility is 36.1 mg/L at 8.4 °C, 28.9 mg/L at 20.4 °C, 23.1 mg/L at 33.4 °C (pH 7)
