48 6.4 0.221 / 0.222
72 6.6 0.224 / 0.225
Conclusions:
At the temperature of measurement (19.9°C to 23.0°C), the water solubility was determined to be 0.222 g/L.
Executive summary:

The purpose of the study was to evaluate the solubility of the test substance in water. The study was carried out in conformity with the OECD test method no. 105. The solubility of a sample of the test item in water was determined using the flask method. Chemical analyses were performed using a high performance liquid chromatographic method. At the temperature of measurement (19.9°C to 23.0°C) the solubility was determined to be 0.222 g/l water.
