Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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. Using a molecular weight of 234.2 g/mole, and the experimentally determined vapour pressure of 1.5 Pa (at 25°C) and water solubility of 11.1 mg/L (at 20°C), the Henry's Law constant at 25°C and at environmental temperature (12°C) is calculated to be 29.5 and 14.1 Pa·m³/mol, respectively. The substance is expected to volatilise from water to some extent (in the OECD TG 309 ca 40% was volatilised).
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 14.1
- 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.
