Description of key information

The structural analogue substance was found to be not inherently biodegradable in an OECD 302B test. Furthermore, the substance showed strong adsorbing properties to activated sludge. Disperse dyes are not considered to be readily biodegradable. Based on the WoE approach referring to the structural analogue substance and the nature of disperse dyes which are not designed to be readily biodegradable, it can be concluded that the target substance is not biodegradable either.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed
