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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 212-828-1 | CAS number: 872-50-4
Bioaccumulation: terrestrial

Description of key information
Based on a measured Log Kow of -0.46 (BASF AG, 1988), the substance does not accumulate in organisms.
Key value for chemical safety assessment
Additional information
According to the criteria for the identification of bioaccumulative (B) and very bioaccumulative (vB) substances as outlined in Regulation (EC) No 1907/2006, Annex XIII section 1.2, the assessment of bioaccumulation shall be based on measured data on bioconcentration in aquatic species.
According to Regulation (EC) No 1907/2006, Column 2 of Annex IX, section 9.3.2 a study on bioaccumulation in aquatic species, preferably fish, does not need to be conducted if the substance has a low potential for bioaccumulation (for instance a Log Kow ≥3). 1-Methyl-2-pyrrolidone (CAS 872-50-4) has a measured log Kow -0.46 (@25°C; BASF AG, 1988), indicating the substance to not accumulate in organisms. Thus no study on bioaccumulation in terrestrial organisms is performed.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
