Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 257-098-5 | CAS number: 51274-00-1 This substance is identified in the Colour Index by Colour Index Constitution Number, C.I. 77492.
Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied
- Principles of method if other than guideline:
- expert judgement
- Conclusions:
- The structural formula of the substance contains none of the functional groups quoted in Appendix 6, Table A 6.1 of the "Recommendations on the Transport Of Dangerous Goods" Manual of Tests and Criteria, fourth revised edition, which may indicate explosive properties. The substance is not explosive.
- Executive summary:
In accordance with section 1 of REACH Annex XI, the study does not need to be conducted. This Iron(III)oxide/hydroxide will not react exothermally with flammable substances due to its chemical structure. The oxidation potential of the Fe 3+ ion is considerably lower than the potential of the reference substances used in UN method O.1 or EC method A17 (see, for instance, CRC Handbook of Chemistry and Physics). Therefore, this compound does not have any oxidizing properties.
Reference
The oxidation potential of the Fe ions ions is considerably lower than the potential of the reference substances used in UN test method O.1 or EC method A17. The iron oxides do not have any hazardous oxidizing properties
Description of key information
In accordance with section 1 of REACH Annex XI, the study does not need to be conducted. This Iron(III)oxide/hydroxide will not react exothermally with flammable substances due to its chemical structure. The oxidation potential of the Fe 3+ ion is considerably lower than the potential of the reference substances used in UN method O.1 or EC method A17. Therefore, this compound does not have any oxidizing properties.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Justification for classification or non-classification
The substance has no oxidising properties; and hence no classification according to both Directive 67/548/EEC and GHS (Regulation EC 1272/2008).
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.
