Description of key information
For the substance no temperature-dependent solubility was observed.
The solubility of the substance at pH 4 and pH7 showed no significant differences. A saltatory increase of solubility was observed when double distilled water and buffer (pH=9) solution was used.
Key value for chemical safety assessment
- Water solubility:
- 400 mg/L
- at the temperature of:
- 20 °C
Additional information
