Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 of the registered substance may be calculated according to general physical principle, from the vapour pressure, molecular weight and water solubility of the substance using the following equation:
HENRY = VP • MOLW / SOL
Explanation of symbols:
- VP = vapour pressure [Pa]
- MOLW = molecular weight [g/mol]
- SOL = solubility [mg/L]
- HENRY = Henry's law constant [Pa m³/mol]
Using a vapour pressure of 3.46 Pa, a molecular weight of 176.26 g/mol and a water solubility of 490 mg/L gives a Henry’s law constant for the registered substance of 1.24 Pa m³/mol.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 1.24
- 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.
