Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Key value for chemical safety assessment
Additional information
Data are available from reliable studies for all required in vitro and in vivo endpoints. Where there was more than one result for an endpoint, the most recent reliable study available was chosen as the key study.
Short description of key information:
In vitro:
Gene mutation (Bacterial reverse mutation assay/Ames test) (OECD 471): positive in selected bacterial strains tested, with or without metabolic activation
Mutagenicity in mammalian cells: positive in HepG2 human hepatoma cell line
Chromosome aberrations in mammalian cells: negative with and without activation
In vivo:
Micronucleus assay in mouse: negative
Endpoint Conclusion:
Justification for classification or non-classification
The body of evidence available for 2-bromopropane indicates that when tested in vitro, 2-bromopropane may induce mutations in bacterial or mammalian cells in certain test strains and cell types, but does not induce chromosome aberrations in mammalian cells. In addition, no significant in vivo increase in frequency of micronucleated polychromatic erythrocytes in bone marrow of mice exposed to 2-bromopropane was observed. Because the in vivo results were negative, it is considered that classification for mutagenicity is not required as described in EC No 1272/2008.
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.
