Results and discussion
Water solubility
- Key result
- Water solubility:
- 3.91 mg/L
- Conc. based on:
- test mat.
- Loading of aqueous phase:
- 1 g/L
- Incubation duration:
- 72 h
- Temp.:
- 20 °C
- pH:
- 5.5
- Details on results:
- The results showed no tendency to increase and the deviation between the incubation times was below 15 %, therefore a valid conduct of the study can be considered.
Corresponding to the analyses the water solubility was determined to be
3.9 mg/L
at a temperature of 20 ± 0.4 °C.

Applicant's summary and conclusion
- Conclusions:
- Corresponding to the analyses the water solubility was determined to be
3.9 mg/L at a temperature of 20 ± 0.4 °C. - Executive summary:
The water solubility of the test item was determined using the shake flask method. The saturation mass concentrations of the test item were determined using U-HPLC / UV - determination.
The results showed no tendency to increase and the deviation between the incubation times was below 15 %, therefore a valid conduct of the study can be considered.
Corresponding to the analyses the water solubility was determined to be
3.9 mg/L at a temperature of 20 ± 0.4 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
