- Key result
- Water solubility:
- 9.33 g/L
- Incubation duration:
- >= 24 - <= 72 h
- Temp.:
- 20 °C
- pH:
- >= 7.1 - <= 7.2
- Details on results:
-Concentration analysed after 24, 48 and 72 hours of stirring: 9.36 g/L, 9.23 g/L and 9.40 g/L, resp.
-Maximum difference meets the criterion of ≤ 15% (i.e. 1.8%)
-The mean of the three concentrations was reported as the water solubility of the substance.- Conclusions:
- The water solubility of the substance at 20°C was determined to be 9.33 g/L.
- Executive summary:
The water solubility of the substance was determined using the flask method in a GLP study according to EC A.6, OECD 105 and OPPTS 830.7840. Quantification was performed by HPLC. The pH of the aqueous samples was between 7.1 and 7.2. From the measurements obtained after 24, 48 and 72 hours of stirring, the mean water solubility at 20°C was determined to be 9.33 g/L.
