Results and discussion

Water solubility
Water solubility:
504 g/L
Temp.:
20 °C
pH:
4.7
Remarks on result:
other: Mean of the concentrations analysed at t=24, 48 and 72 h: 466 g/L, 519 g/L and 528 g/L , resp.
Details on results:
The maximum difference of the concentrations determined in the 24, 48 and 72 hour test samples was = 15% (12% was calculated).

A small response at the retention time of the test substance was detected in the chromatogram of the pretreated sample from the blank water mixture. Taking the dilution factors into account, the maximum contribution of the response to the test samples was 8.2E-06 %. It was considered not to have significant effect on the study results.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L)
In a GLP-compliant study in accordance with EC A.6, OECD 105 and OPPTS 830.7840 using the flask method, the water solubility of the substance at 20°C has been determined as 504 g/L. The pH of the saturated solution was 4.7.
