- 143 mg/L
- Conc. based on:
- test mat. (dissolved fraction)
- Temp.:
- 20 °C
- pH:
- >= 7.21 - <= 7.25
- Conclusions:
- The solubility of test item in ultrapure water was determined according to the OECD Guideline No. 105 (flask method), EU Method A.6 (Water Solubility) and EPA OPPTS 830.7840 (Water Solubility). The solubility of test item in ultrapure water at 20 °C was determined to be 143 mg/L.
- Executive summary:
The water solubility of test item was determined according to OCED 105 guideline using the flask method with GC-FID analysis.
The result is 143 mg/L at 20°C and pH 7.2.
Reference
The concentration of test item solutions in aqueous phase were 121 (48 h), 144 (72 h) and 143 (96 h), respectively. The pH values of the solutions in ultrapure water were pH 7.21 (48 h), pH 7.25 (72 h) and pH 7.24 (96 h), respectively. Test temperature was 20.0 °C - 20.1 °C. There is no significant change of the measured concentrations after 72 h and 96 h. Thus, it can be concluded that equilibrium is reached. Thus, the results obtained after 72 h and 96 h were averaged, to give the water solubility of test item. The solubility of test item in ultrapure water at 25 °C: 143 mg/L.
Description of key information
The water solubility of test item was determined according to OCED 105 guideline using the flask method with GC-FID analysis.
The result is 143 mg/L at 20°C and pH 7.2.
Key value for chemical safety assessment
- Water solubility:
- 143 mg/L
- at the temperature of:
- 20 °C
Additional information
A reliable experimental study, conducted according to a recognized OECD method and under GLP, is available. It is considered as a key study.
