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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Henry coefficient can be calculated using: Vapour Pressure (Pa) x Molecular weight (kg/Mol) / WS (kg/l). Using this equation, the following values were determined: Henry coefficient at 25°C is 3.923 Pa-m3/mole and the Henry coefficient under environmental conditions at 12°C is 1.88Pa-m3/mole (converted with EUSES). This Henry coefficient shows that volatilisation is of minor importance in the environmental behaviour of the substance (see also distribution modelling).
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 4.202
- at the temperature of:
- 25 °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.
