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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Not relevant, very low value assumed
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0
- at the temperature of:
- 12 °C
Additional information
This endpoint is covered by the category approach for soluble iron salts (please see the section on physical and chemical properties for the category justification/report format). Volatilisation as expressed by Henry's Law constant is not a relevant property of metals, except organometallic compounds and a few exemptions such as mercury. Since no formation of volatile organometallic iron compounds is assumed, the Henry coefficient should be set to a very low value (i.e. 0.000'004 Pa∙m³/mol according to ECHA 2008, Guidance on information requirements and chemical safety assessment, Appendix R.7.13 -2: Environmental risk assessment for metals and metal compounds, p 12) when needed in calculations.
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.
