Results and discussion
Water solubility
- Key result
- Water solubility:
- 0.032 g/L
- Conc. based on:
- test mat.
- Incubation duration:
- >= 24 - <= 72 h
- Temp.:
- 20 °C
- pH:
- 7.1
- Details on results:
- -Maximum difference of the concentrations determined in the 24, 48 and 72 hour test samples meets the criterion of ≤ 15% (i.e. 7.1%)
-The mean of the concentrations after 24, 48 and 72 h was therefore reported as the water solubility of the substance.
-No test item was detected in the pretreated sample from the blank.

Applicant's summary and conclusion
- Conclusions:
- The water solubility of the substance at 20°C was determined to be 0.0319 g/L.
- Executive summary:
The water solubility of the substance was determined using the flask method based on EC A.6, OECD 105 and OPPTS 830.7840. The study was performed directly at the test temperature of 20°C.
Quantification was performed by HPLC. The pH of the aqueous samples was 7.1. From the measurements obtained after 24, 48 and 72 hours of stirring, the water solubility at 20°C was determined to be 0.0319 g/L.
