Description of key information
Water solubility: 0.017474 - 0.000040711 mg/L (QSAR)
Key value for chemical safety assessment
- Water solubility:
- 0.017 mg/L
- at the temperature of:
- 25 °C
Additional information
The substance was is hydrolytically unstable as noted in a pre-testing on water solubility prior to a final OECD 105 study. This property was also verified by a hydrolysis study, where the substance showed almost complete hydrolysis within 14 h under physiological conditions.
Therefore, water solubility was estimated in a weight-of-evidence approach from the calculated values of the containing compounds and a representative theoretical structure which were found to be in the range of 0.017474 - 0.000040711 mg/L. The value of 0.017474 mg/L is used for risk assessment.
