Type of information:
experimental study
Adequacy of study:
key study
Study period:
November 30, 2015
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
OECD Guideline 105 (Water Solubility)
GLP compliance:
Type of method:
flask method
Water solubility:
ca. 103.04 g/L
Conc. based on:
test mat.
20 °C
ca. 3.51
Remarks on result:
other: pH mother solution = 4.66; pH satured solution = 3.51
Details on results:
Reference solutions were measured in the spectrophotometer in quantitative mode, thus generating a calibration curve. Calibration curve was smooth and linear at every concentration. Considering that preliminary test resulted in an absorbance keeping the same shape like the references, its value was considered for the 24 hours’ measurement (test 1). Adjusting concentrations in proportion to the real weights the following results were obtained:
test 1 (24 hs) 103.94 g/l
test 2 (48 hs) 104.96 g/l
test 3 (96 hs) 100.23 g/l
average solubility 103.04 g/l
standard deviation 2.49
pH mother solution 4.66
pH satured solution 3.51
Average solubility at 20°C is 103.04 g/l: pH of saturated solution is 3.51.
Executive summary:


Solubility test was performed following OECD guideline 105.


Average solubility: 103.04 g/l at 20°C and pH 3.51.
