Expiration Date: December 31, 2018 - Key result
- Water solubility:
- 0.89 g/L
- Conc. based on:
- test mat.
- Incubation duration:
- 10 min
- Temp.:
- 20 °C
- pH:
- 5.79
- Conclusions:
- The water solubility was determined to be 0.89 g/L
- Executive summary:
In a GLP guideline study conducted by the Shake Flask Method (direct visual observation without analytical determination) according to the preliminary assessment procedures in OPPTS 830.7840, OECD TG 105, and EC Test Method A6, the water solubility was determined to be 0.89 g/L. Due to the absence of a valid analytical method or analytical reference standard, only a visual assessment of solubility could be made.
