Results and discussion
Water solubility
- Water solubility:
- 0.4 µg/L
- Temp.:
- 24 °C
- pH:
- ca. 7
- Details on results:
- The value given refers to room temperature (24-25 °C, see above) and represents the mean from 3 determinations (sigma = 0.2). Individual values were: 0.2, 0.6 and 0.3 µg/L.
Applicant's summary and conclusion
- Conclusions:
- The test substance is practically insoluble in water (< 0.1 mg/L)
- Executive summary:
The water solubility of the test substance was determined using HPLC with UV-vis detection. The water solubility at 24 -25 °C was 0.4 µg/L.
