Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
The Henry's law constant is calculated using the equation from EUSES: 405 Pa·m³/mol at 25oC (using a Vapour pressure of 100 Pa, a molecular weight of 0.18231 kg/mol, and water solubility of 0.042 g/L (at 20°C). The Henry's law constant at environmental temperature (12°C) is calculated to be 194 Pa·m³/mol (using a vapour pressure of 39.8 Pa, a molecular weight of 0.182 kg/mol and a water solubility of 0.0374 g/L). It can be concluded that once emitted to the water compartment the substance will partition from water to air.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 194
- at the temperature of:
- 12 °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.
