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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 tetrasodium (E)-7-((4-(4-chloro-6-(3-(2-(sulfooxy)ethylsulfonyl)phenylamino)-1,3,5-triazin-2-ylamino)-2-ureidophenyl)diazenyl)naphthalene-1,3,6-trisulfonate and (E)-7-((4-(4-chloro-6-(3-(2-(sulfooxy)ethylsulfonyl)phenylamino)-1,3,5-triazin-2-ylamino)-2-ureidophenyl)diazenyl)naphthalene-1,3,6-trisulfonic acid

Description of key information
Not readily biodegradable
Key value for chemical safety assessment
Additional information
No experimental data are available for the target substance, thus the information on the Similar Substance 03 has been taken into account. The structural differences occurring between the target substance and Similar Substance 03 are not expected to significantly impact the biodegradability properties, thus the read across approach can be considered as representavive and appropriate (further details in the document attached to the IUCLID section 13).
Similar Substance 03 was tested for biodegradation in anaerobic conditions according to the ISO 11734.
The formation of gas within 56 days remained below 20 % of the theoretical maximum. A significant anaerobic biodegradation was not observed and the test iem results to be not readily biodegradable.
Considerng the high similarity between the substances and their chemical family (the both substances are dystuff), the target substance can be considered as not readily biodegradable.
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.
