Description of key 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. [Rosenblatt DH et al; Problem Definition Studies on Potential Environmental Pollutants II U.S. Army Medical Bioeng Res Devel Lab Fort Detrick. Frederick, MD AD AO30428 pp. 7, C1 -C7 (1975)]
Key value for chemical safety assessment
- Water solubility:
- 20 000 mg/L
- at the temperature of:
- 20 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
