Results and discussion

Water solubility
Water solubility:
8.1 µg/L
Temp.:
23 °C
pH:
ca. 7
Details on results:
The value given refers to room temperature (23-24 °C, see above) and represents the mean from 3 determinations (sigma = 3.3). Individual values were: 4.8, 8.3 and 11.3 µg/L.

Applicant's summary and conclusion

Conclusions:

The test substance is practially insoluble in water (< 0.1 mg/L)
Executive summary:

The water solubility of the test substance was determined using UV-vis spectrometry. The water solubility at 23-24 °C was 8.1 µg/L.
