Results and discussion
Water solubility
- Water solubility:
- 1 460 mg/L
- Temp.:
- 20 °C
- pH:
- >= 5.47 - <= 5.94
- Details on results:
- The water solubility of the test item is given as the mean of the measured saturation concentration of the test substance dissolved in water following 1 day, 2 days and 3 days of equilibration, if these concentration values do not differ by more than 15%. The mean of the test item concentrations in the water samples obtained after 1 day, 2 days and 3 days equilibration was 1.46 mg/mL (1460 mg/L) with relative standard deviation 2.21%.
Applicant's summary and conclusion
- Conclusions:
- Water solubility is 1.46 ± 0.08 mg/mL at 20 ± 1°C (1460 mg/L)
- Executive summary:
The water solubility was determined using the flask method according to OECD Guideline 105. The test item was dissolved in water at 30°C for up to 3 days. When saturation was achieved the mixture was cooled and kept at the equilibration temperature (20°C) for 24 hours. Subsequently, the mass concentration of the substance in the aqueous solution was determined by HPLC.
The mean of the test item concentrations in the water samples obtained after 1 day, 2 days and 3 days equilibration was 1.46 mg/mL (1460 mg/L) with relative standard deviation 2.21%.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
