Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The Henry's Law Constant (H) for the test substance has been calculated by approximating by the ratio of the vapour pressure to the water solubility at the same temperature
- GLP compliance:
- no
- Key result
- H:
- 0.478 Pa m³/mol
- Temp.:
- 20 °C
- Conclusions:
- Henry's Law Constant (H) = 0.478 Pa m3/mol
- Executive summary:
The Henry's Law Constant (H) for the test substance has been calculated by approximating by the ratio of the vapour pressure to the water solubility at the same temperature.
Vapour pressure at 20°C (293K): 1.43 x 10-3Pa
Water solubility at 20°C (293K): 1.05 mg/L
Henry's Law Constant (H) = 0.478 Pa m3/mol
It is therefore concluded that the test substance will show a moderate tendency for volatilisation from dilute solution.
