Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 25 Jun - 6 Aug 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- GLP compliance:
- no
- Type of method:
- flask method
- Water solubility:
- 1 003.83 mg/L
- Temp.:
- 20.25 °C
- pH:
- 7
- Details on results:
- Based on the result of the preliminary test, the solubility of the material was estimated to be between 200 mg/l and 1000 mg/l, therefore the shake flask method was chosen for the definitive test.

Since the results for Flask 1 were significantly different comparing to respective results for Flasks 2 and 3, they were discarded and the average solubility was determined taking into account Flasks 2 and 3 only. Difference between them was 8.27% and it was considered acceptable. Temperature in case of Flask 2 was 20.2 °C, for Flask 3 20.3 °C, respectively, thus the mean temperature was 20.25 °C. pH was 7 for both flasks.
Description of key information
1003.830 mg/L at 20.25 °C, pH 7 (OECD 105)
Key value for chemical safety assessment
- Water solubility:
- 1 g/L
- at the temperature of:
- 20 °C
Additional information
For the water solubility determination, flask method was used.
