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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
FeCl3: Anhydrous ca. 2.9; Hexahydrate ca. 1.8, solution (40 %) 1.4
Key value for chemical safety assessment
- Relative density at 20C:
- 2.9
Additional information
- BASF AG (1988). Safety data sheet: Anhydrous iron chloride (2/88). Self-publishe
A number of densities, relative densities and bulk densities are available from the literature for different hydration states and solutions. The data on bulk density comprise 1000 kg FeCl3/m³ (BASF 1988). The following table gives an overview on the remaining information.
Table: Relative densities or densities [g/cm³] under standard pressure (ISO 5011, i.e. 101.3 kPa)
| Category member, Molecular Formula | Anhydrous form | Solid hydrate form | Aqueous solution |
| Ferric chloride, FeCl3 | 2.90 at 4-25 °C | Hexahydrate (CAS 10025-77-1): 1.8 at 20 °C | 1.42 at 20 °C, 40 % |
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.
