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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Accumulation in organisms is not to be expected.
Key value for chemical safety assessment
Additional information
No experimental data are available for the assessment of the bioaccumulation potential of 1-methyl-1H-imidazole (CAS 616-47-7).
Based on the low log D values (pH 5 = -0.655; pH 7 = -0.029; pH 9 = 0.096; SPARC, BASF, 2021; see IUCLID Ch. 4.7) and the substance’s low n-octanol/water partition coefficient of -0.19 (25°C; BASF AG, 1989; 104547/01) for the uncharged molecule, accumulation in organisms is not to be expected.
Therefore, in accordance with column 2 of REACH Annex IX section 9.3.2 and for reasons of animal welfare, a study on bioaccumulation is not provided.
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.
