Results and discussion

Water solubility
Water solubility:
1.9 µg/L
Temp.:
25 °C
pH:
7.2
Details on results:
The value given refers to room temperature (24-25 °C, 25°C given here) and represents the mean from 3 determinations (sigma = 0.4). Individual values were: 1.6, 1.7 and 2.3 µg/L. pH values for the 3 determinations were 7.2, 7.3 and 7.0 (mean of 7.2 given above).

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
The test substance is insoluble in water.
Executive summary:

The water solubility of the test substance was determined by UV-vis spectrometry to be 1.9 µg/L at 24 -25°C.
