Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Test material

Constituent 1
Chemical structure
Reference substance name:
4,4'-[1,3-phenylenebis(azo)]bisbenzene-1,3-diamine
EC Number:
213-888-1
EC Name:
4,4'-[1,3-phenylenebis(azo)]bisbenzene-1,3-diamine
Cas Number:
1052-38-6
Molecular formula:
C18H18N8
IUPAC Name:
4,4'-(1E,1'E)-1,3-phenylenebis(diazene-2,1-diyl)dibenzene-1,3-diamine
Specific details on test material used for the study:
The analyzed azo dye presents one azo bonds that can have a clevage with consequent generation of amine mutagenic products (Øllgaard et al., 1998; Weber and
Adams,1995).

Results and discussion

Remarks on result:
mutagenic potential (based on QSAR/QSPR prediction)

Any other information on results incl. tables

The azo cleavage produces three mutagenic amines.

Applicant's summary and conclusion

Conclusions:
Mutagen, there are three generated amines after the cleavage of the azo bonds; all are predicted mutagen
