Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Henry's Law constant
Administrative data
Link to relevant study record(s)
- Endpoint:
- Henry's law constant
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- supporting study
- Study period:
- 2023
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Principles of method if other than guideline:
- The Henry´s Law Constant of the substance was calculated by using the computer program EUSES v2.2. This parameter is calculated from temperature corrected experimental vapour pressure and water solubility.
- GLP compliance:
- no
- Key result
- H:
- 0.005 Pa m³/mol
- Temp.:
- 25 °C
- H:
- 0.003 Pa m³/mol
- Temp.:
- 12 °C
- Remarks on result:
- other: Henry's law constant calculated at environmental temperature
- Conclusions:
- A scientifically accepted calculation method is used to determine the Henry´s Law Constant with EUSES v2.2. No GLP criteria are applicable for the usage of this tool and the estimation is easily repeatable. The Henry's Law Constant of the substance was estimated to be 5.49E-03 Pa m³/mol at 25 °C and estimated from the ratio of the vapour pressure (1.7 Pa at 20°C) and the water solubility (100 g/L at 20°C).

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
