Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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

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)
