Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

The ready biodegradability of 2-NP was assessed in screening tests.

Key value for chemical safety assessment

Additional information

2-NP is not readily biodegradable. Only a small amount of biodegradation was observed in screening tests (supporting studies). In OECD 301D closed bottle or equivalent tests, biodegradation ranged from not detected to 8 to 14% after 28 days. In a study in which radiolabeled 2-NP was added to activated sludge, 0.8% CO2 was produced in 5 days. These results are consistent with a read across approach with 1 -nitropropane (key study) which was not readily biodegradable.
