pH 5 buffer: 6.93±1.04 mg/L (C. of V. =15.0%)
pH 7 buffer: 7.86±1.04 mg/L (C. of V. =13.2%) - Conclusions:
- Water solubility at 20°C
Purified water: 9.08 mg/L
pH 5 buffer: 6.93 mg/L
pH 7 buffer: 7.86 mg/L - Executive summary:
The study was conducted to determine the water solubility of the test substance according to regulatory guidelines: OECD 105 and EEC Method A.6.
Water solubility at 20°C
Purified water: 9.08±0.47 mg/L (C. of V. =5.2%)
pH 5 buffer: 6.93±1.04 mg/L (C. of V. =15.0%)
pH 7 buffer: 7.86±1.04 mg/L (C. of V. =13.2%)
Tests for the solubility of the test substance in pH 9 buffer solution were not considered relevant due to known rapid hydrolysis of the test material at this pH.
