- Type of method:
- flask method
- Key result
- Water solubility:
- 470.2 g/L
- Conc. based on:
- test mat.
- Incubation duration:
- 3 d
- Temp.:
- 20 °C
- pH:
- >= 4.42 - <= 6
- Conclusions:
- The water solubility of the test item was determined to be 470.2 g/L ± 3.6 %. The result is also applicable for the water free form of the test item.
- Executive summary:
A study was performed according to OECD TG 105 and Regulation (EC) No. 440/2008 method A.6 in order to determine the water solubility of the test item in water by using the flask method (analytical method: HPLC). The mean water solubility was determined to be 470.2 g/L ± 3.6 %. All replicates showed good correspondence. Equilibration was considered to be reached after 1 day. No observations arising doubts concerning the accuracy of the results and the validity of the study were made. The result is also applicable for the water free form of the test item.
