Description of key information

The water solubility of the test substance cannot be determined due to the quick hydrolysis of the test substance (half life time < 4 minutes). The water solubility of MPKO, the hydrolysis product of OS9600, was determined to be 34.7 g/L at 19.8°C and pH of 7.4.

Key value for chemical safety assessment

Water solubility:
34.7 g/L
at the temperature of:
19.8 °C

Additional information

Data waiving (study technically not feasible): The test substance hydrolyses quickly (half life time < 4 minutes) and therefore, the water solubility cannot be determined.

Supporting study: The water solubility of the analogue substance MPKO was determined using the flask method in accordance with OECD Guideline 105 and EU Method A.6. The water solubility was 34.7 g/L at 19.8 ºC and pH of 7.4.
