Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

1-Methylpyrrolidine was easily eliminated from water in an inherent biodegradation test (similar to OECD 302 B), but no biodegradation was observed on a study conducetd comparable to OECD Guideline 301F.

Key value for chemical safety assessment

Biodegradation in water:
inherently biodegradable

Additional information

To assess the biodegradability of the test substance, a study was conducted similar to the Zahn-Wellens inherent biodegradability test (OECD Guideline 302 B). The DOC removal was found to be >70 % and therefore it was concluded that the test substance can be easily eliminated from water.

In a second study conducted similar to OECD Guideline 301F, the BOD5/COD ratio of the test substance was found to be <1 %. This test result indicates that the substance is poorly biodegradable.
