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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reaction mass of copper complex of [(2,6-difluoroheterocycl-4-yl)amino]hydroxy{[2-hydroxy-3-sulfonato-5-(vinylsulfonyl)phenyl]diazenyl}naphthalene sulfonic acid, dialkali salt and copper complex of [(2,6-difluoroheterocycl-4-yl)amino]-hydroxy{[2-hydroxy-3-sulfonato-5-{[2-(sulfonatooxy)ethyl]sulfonyl}phenyl]diazenyl}naphthalene sulfonic acid, trialkali salt

Description of key information
In accordance with Column 2 of Annex VII Section 7.13 of the REACH regulation this endpoint has been omitted. The substance does not contain halogen or nitrogen atoms which are chemically bound to oxygen.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
No tests were performed because oxidizing properties of the test substance can be excluded:
- The compound contains oxygen and fluorine chemically bonded to carbon, so for this case the testing procedure for oxidizing substances need not to be applied (see the "Recommendations on the Transport of Dangerous Goods I Manual of Tests and Criteria" (ST/SG/ AC.1 0/11 /Rev.3), page 401).
- Oxygen is also present as a copper(ll)-salt of phenol/naphthol. A representative example for an organic copper salt (with more oxygen and less carbon atoms coming on one copper-Il-ion) is copper(ll) acetate, which is not classified as an oxidizing substance according to RID/ADR class 5.1.
- Further there is an aliphatic-aromatic sulfone group. Representative examples for this structure are diethylsulfone and diphenylsufone, which both are not classified as oxidizing substances according to RID/ADR class 5.1.
- There are also sodium sulfonate groups and a sodium sulfate group: For possible oxidizing properties of this oxygen-rich groups a comparison was made with p-toluenesulfonic acid sodium salt and with sodium sulfate, which both have no oxidizing properties according to RID/ADR class 5.1.
- Further there is nitrogen present in a diaryl amine structure and in a pyrimidine structure., which both don't have oxidizing properties, as it can be proofed by representative examples for these structures, i.e. diphenylamine and pyrimidine, which are not classified as oxidizing substances according to RID/ADR class 5.1.
- Nitrogen is also present in an azo structure. Here oxidizing properties can also be excluded. This is proofed by a representative example for this structure, i.e. azobenzene, which is not classified as an oxidizing substance according to RID/ADR class 5.1.
The test substance is not expected to have oxidizing properties in the sense of Guideline 92/69/EEC, test A.17 .
Justification for classification or non-classification
In accordance with Column 2 of Annex VII Section 7.13 of the REACH regulation this endpoint has been omitted. The substance does not contain halogen or nitrogen atoms which are chemically bound to oxygen.
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).
