- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7840 (Water Solubility)
- Version / remarks:
- 1998
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- flask method
- Key result
- Water solubility:
- 9.7 mg/L
- Conc. based on:
- other: peak area of the largest substance peak in the chromatogram
- Temp.:
- 20 °C
- pH:
- >= 6.4 - <= 6.9
- Details on results:
The concentration analysed after 24, 48 and 72 hours of stirring was 11.2 mg/L, 9.34 mg/L and 10.1 mg/L, resp.
The 24-hour measurement was higher than the 48- and 72- hour measurements (maximum difference of > 15%). The water solubility of the test substance was therefore calculated as the mean value of the 48- and 72-hour measurements (maximum difference of 8.2%).
No test substance was detected in the pretreated sample from the blank.- Conclusions:
- The water solubility at 20°C of the substance PEMP product was determined to be 9.74 mg/L.
- Executive summary:
The water solubility of the substance PEMP product was determined using the slow-stirring flask method in a GLP study according to EC A.6, OECD 105 and OPPTS 830.7840. Quantification was performed by UPLC-MS-MS using the area of the largest peak in the chromatogram. From the measurements obtained after 48 and 72 hours of stirring, the water solubility at 20°C was determined to be 9.74 mg/L. pH of the saturated water phase: 6.4 - 6.9.
