- Details on results:
- CALIBRATION
- Six concentration levels were used: 1, 2, 5, 20, 50 and 100 μg/mL. The calibration graph was calculated applying quadratic regression using 1/concentration as weighting factor.
RESULTS OF THE SHAKE FLASK METHOD
- pH of the samples varied in the range of 6.24 to 6.26.
- Samples were analysed with the LC-MS method.
- Based on the measured concentrations the test mixtures were homogeneous.
- Based on the measured concentrations the saturation reached after three days. In the summary calculation the day four, five and six results were used. - Conclusions:
- Under the conditions of this study, the water solubility of the test material was determined to be 5.05 ± 0.104 mg/mL (95 % confidence interval) at 20 °C ± 0.5°C using the shake-flask method.
- Executive summary:
The water solubility of the test material was determined in accordance with the standardised guidelines OECD 105 and EU Method A.6 under GLP conditions.
Water solubility was investigated using the shake-flask method. The test material was dissolved in water at a temperature somewhat above the test temperature. Then saturation is achieved the mixture is cooled and kept at the test temperature, as long as necessary to reach equilibrium. Subsequently, the mass concentration of the test material in the aqueous solution was determined by analytical methods. Before the LC-MS analysis the samples were diluted with methanol.
At first the test was performed with one, two and three days saturation time. The result showed that three days was not enough to reach the saturation. Therefore, the test was repeated with longer saturation time (6 days).
Under the conditions of this study, the water solubility of the test material was determined to be 5.05 ± 0.104 mg/mL (95 % confidence interval) at 20 °C ± 0.5°C using the shake-flask method.

Additional information
The water solubility of the test material was determined in accordance with the standardised guidelines OECD 105 and EU Method A.6 under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Water solubility was investigated using the shake-flask method. The test material was dissolved in water at a temperature somewhat above the test temperature. Then saturation is achieved the mixture is cooled and kept at the test temperature, as long as necessary to reach equilibrium. Subsequently, the mass concentration of the test material in the aqueous solution was determined by analytical methods. Before the LC-MS analysis the samples were diluted with methanol.
At first the test was performed with one, two and three days saturation time. The result showed that three days was not enough to reach the saturation. Therefore, the test was repeated with longer saturation time (6 days).
Under the conditions of this study, the water solubility of the test material was determined to be 5.05 ± 0.104 mg/mL (95% confidence interval) at 20 °C ± 0.5°C using the shake-flask method.
