Results and discussion

Water solubility
Water solubility:
< 0.006 mg/L
Temp.:
20 °C
pH:
6.26
Details on results:
The water solubility was below the limit of detection of 0.00572 mg/L in all six determinations. The pH given is the mean from six determinations (range: 5.96-6.67)

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
The water solubility of the test item at 20°C was below the limit of detection (<0.00572 mg/L).
Executive summary:

The water solubility was determined in a guideline study using saturation mass concentration with analysis by HPLC. The water solubility was below the limit of detection (<0.00572 mg/L) at 20°C.
