Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key value for chemical safety assessment
- Water solubility:
- 9 400 mg/L
- at the temperature of:
- 80 °C
Additional information
Water solubility of gases is typically measured in a closed system, under pressure, to achieve saturation in water. A value of 9400 mg/L is reported and was measured at elevated temperature (80°C) and pressure 3.4 mPa. This value represents a worse case, highest water solubility value for the substance and under environmental conditions at lower temperature and pressure the water solubility is expected to be lower. In addition,in open systems, the solubility of this gaseous substance is also significantly lower due to its volatility (vapor pressure = 1.71E6 Pa at 25°C). The HL using this high water solubility value demonstrates that the substance will compartmentalize into air. Therefore, the solubility value still represents a much higher concentration than would ever be expected under environmental conditions.
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.
