Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 5,5'-{(phenylmethanediyl)bis[benzene-4,1-diyl-diazene-2,1-diyl]}bis{1-[3-(dimethylamino)propyl]-4-methyl-6-oxo-3-(pyridinium-1-yl)-1,6-dihydropyridin-2-olate} hydrochloride and 5,5’-[3,4’-(phenylmethanediyl)diphenylene]bis(diazene-2,1-diyl)bis{1-[3-(dimethylamino)propyl]-4-methyl-6-oxo-3-(pyridinium-1-yl)-1,6-dihydropyridin-2-olate} hydrochloride
EC number: 700-312-3 | CAS number: -
Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The substance registered is considered to be neither readily nor inherently biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Two valid on ready and inherent biodegradability, respectively, were being conducted on the analogue substance.The analogue substance was investigated for its ready biodegradability and inherent biodegradability via OECD guideline-conform studies. The applicability of the read across approach had been confirmed by the registrant via an expert statement (see IUCLID chapter 13). In both studies the analogue substance was not biodegradable under the test conditions within 28 days. Based on the applicability of the proposed read across approach, the same biodegradation properties are likely to apply to the substance registered as well.
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.
