Flask 1, 2, 3: 5.9721 g was added to 100 ml water and then the flask was shaken for 24, 48, 72 hours, respectively. Full saturation was not achieved in Ffask 1 indicating 24 hours is not sufficient for saturation, therefore only determinations from flasks 2 and 3 have been used.
Description of key information

- Water solubility:
- 8.682 g/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of the substance was determined according to EU Method A.6 (flask method).
