- 123 mg/L
- Temp.:
- 20 °C
- pH:
- 5
- Details on results:
- Preliminary test:
- The saturation concentration of the test substance at room temperature was estimated to be greater than 0.1 g/L.
Definitive test:
- The mean water solubility (n=5) was determined to be 123 mg/L at 20 +/- 1 deg C and pH 5 (SD: 3.6 mg/L).
Any other information on results incl. tables
Sample #2, which was shaken at 30 deg C for 75 min, was not analyzed by HPLC.
