Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Executive summary:

The structure activity relationship of the substance was investigated by using the QSAR Toolbox 4.3.1 (released 2019).

The QSAR Toolbox refers to 'primary aromatic amines, hydroxyl amines and their derived esters' with regard to mutagenicity and carcinogenicity.
