- Key result
- Water solubility:
- 0.103 mg/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- pH:
- >= 7.7 - <= 7.8
- Remarks on result:
- other: mean value (maximum difference=7.7%)
- Details on results:
- The coefficient of variation (CV) (n=10) was ≤ 30% at both flow rates. It demonstrated that the system was equilibrated at all flow rates.
The maximum difference on the mean values at both flow rates was ≤ 30%. The water solubility of the substance is given as the mean value of these measurements: 0.103 mg/L. - Conclusions:
- The water solubility of the substance at 20°C was determined to be 0.103 mg/L.
- Executive summary:
The water solubility was determined using the column elution method in a GLP study according to EC A.6, OECD 105 and OPPTS 830.7840.
Quantification was performed by GC-MS-MS. The water solubility of the substance at 20°C was determined to be 0.103 mg/L. The pH of the aqueous samples was 7.7 - 7.8.
Reference
No test substance was detected in the samples from the blank column.
Description of key information
The water solubility of the substance at 20°C was determined to be 0.103 mg/L.
Key value for chemical safety assessment
- Water solubility:
