Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Potassium bromide is an inorganic salt that dissociates to its composite ions in aqueous solutions at environmental pH and temperature. Comparison of the available data on the various bromide salts have shown that the bromide ion is the relevant ion for determination of the toxicological profile with simple cations such as potassium, sodium or ammonium, that are ubiquitous in nature, having little or no influence on the bromide ion properties. It is therefore justified to read-across data from other inorganic bromide salts to potassium bromide.
The in vitro bacterial mutation test with potassium bromide was negative.
All tests with sodium bromide were negative (in vitro bacterial mutation test, in vitro mammalian cytogenetic test, in vitro Unscheduled DNA Synthesis in mammalian cells).
Based on all these results, potassium bromide does not need to be classified with regard to mutagenicity.
Short description of key information:
The in vitro bacterial mutation test with potassium bromide was negative.
All tests available with sodium bromide were negative (in vitro bacterial mutation test, in vitro mammalian cytogenetic test, in vitro Unscheduled DNA Synthesis in mammalian cells).
Endpoint Conclusion: No adverse effect observed (negative)
Justification for classification or non-classification
The substance is not mutagenic.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
