Description of key information

half life (50% degradation) of 4,4'-bis(dimethylamino)-4''-(methylamino)trityl alcohol in water is 180 days and in sediment is 1600 days.
These results suggests that the substance is not readily biodegradable in water and sediment given its persistence in the environmental segments.

Key value for chemical safety assessment

Half-life in freshwater:
180 d
Half-life in freshwater sediment:
1 600 d

Additional information

half life (50% degradation) of 4,4'-bis(dimethylamino)-4''-(methylamino)trityl alcohol in water is 180 days and in sediment is 1600 days. These values exceeds the EPA criteria of  < 2 months (< 60 days) for Biodegradation in water and sediment hence these results suggests that the substance is not readily biodegradable in water and sediment given its persistence in the environmental segments.
