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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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:
- key study
- Study period:
- No data
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Calculated from the measured water solubility of the substance and measured vapour pressure for the test substance
- GLP compliance:
- no
- Key result
- H:
- 0.065 Pa m³/mol
- Temp.:
- 25 °C
- Conclusions:
- Henry's law constant was calculated to be 0.065 Pa.m3/mol at 25 °C based on experimental water solubility (100 g/L at 20°C or 107 g/L at 25°C) and experimental vapour pressures (17 Pa at 20°C or 24 Pa at 25°C) for the test substance. The value indicates that a low rate of volatilisation from surface water is expected.

Description of key information
Henry's law constant was calculated to be 0.0647 Pa.m3/mol at 25 °C based on experimental water solubility and experimental vapour pressures for the test substance. The value indicates that a low rate of volatilisation from surface water is expected.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0.065
- 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.
