Description of key information
The substance 5-nitro-o-anisidine degrades 87.6% in water in 28 days and thus it can be concluded that 5-nitro-o-anisidine is readily biodegradable in water. Also the half life of 5-nitro-o-anisidine is less than 60 days thus it is not persistent in water.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Based on the information collected from various sources for the biodegradation in water for 5-nitro-o-anisidine it was estimated that 5-nitro-o-anisidine degrades 87% in 28 days thus it can be concluded that 5-nitro-o-anisidine is readily biodegradable in water medium.

Based on the above information it can be concluded that the substance is readily biodegradable. Also the half life of 5-nitro-o-anisidine is less than 60 days the threshold criteria for persistence it can be concluded that 5-nitro-o-anisidine is not persistent in water according to criteria of CLP regulation.
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).
