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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 constant H of Henry’s Law can b ecalculated from its vapour pressure and water solubility as follows:
Calculation of H = Henry’s Law Constant
H = p x MW/c [kPa m³/mol]
p = vapour pressure [kPa]
MW = molecular weight [g/mol]
C = solubility in water [g/m³]
Vapour pressure is 1.1E-11 kPa at 25°C and was taken from section 4.8
Water soubility is 11300 g/m³ at 25°C and was taken from section 4.6
Molecular weight of the substance is 261.28 g/mol
The resulting H is 2.5E-13 kPa m³/mol
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0
- 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.
