water solubility
Type of information:
experimental study
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
equivalent or similar to guideline
OECD Guideline 105 (Water Solubility)
not applicable
Principles of method if other than guideline:
There is experimental information that a 60.97% solution can be prepared and hence the substance is considered to be readily soluble in water.
GLP compliance:
Type of method:
other: the method was not reported but considering the high water solubility, it is very likely that a method similar to the flask method has been used.
Water solubility:
>= 60.97 other: percent
Conc. based on:
test mat.
Remarks on result:
other: temperature and pH not reported
Water solubility: at least up to 60.97%.
