Key value for chemical safety assessment

Water solubility:
20 000 mg/L

Additional information

For water solubility only limited information is available. The value of >20 g/L has been reported by the US Army in the 1970s based on intense research on chemical warfare agents. The data have been peer reviewed and are taken forward to most important data bases dealing with PC parameters of chemical, toxicological and ecotoxicological data or general risk assessments.
