Results and discussion

Water solubility
Key result
Water solubility:
0.041 g/L
Incubation duration:
>= 24 - <= 48 h
Temp.:
20 °C
pH:
6.7
Details on results:
- Concentration analysed after 24, 48 and 72 hours of stirring: 0.0440 g/L, 0.0386 g/L and 0.0267 g/L, resp.
- The 72-hour measurement was significantly lower than the 24- and 48- hour measurements (maximum difference > 15%).
- The water solubility of the test item was given as the mean value of the 24- and 48-hour measurements; the maximum difference meets the criterion of ≤ 15% (i.e. 13%).

Applicant's summary and conclusion

Conclusions:
The water solubility of the substance at 20°C was determined to be 0.0413 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 LC-MS/MS. Concentration analysed after 24, 48 and 72 hours of stirring: 0.0440 g/L, 0.0386 g/L and 0.0267 g/L, resp. The pH of the aqueous samples was 6.7.

The water solubility of the test item was given as the mean value of the 24- and 48-hour measurements; the maximum difference meets the criterion of ≤ 15% (i.e. 13%).

The water solubility at 20°C was determined to be 0.0413 g/L.
