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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Abiotic degradation / hydrolysis
According to Annex IX of REACH Regulation, information on hydrolysis is not required for inorganics
Biodegradation in water: screening test, Biodegradation in water and sediment, Biodegradation in soil
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex VII, section 9.2.1.1, a Biodegradation test does not need to be conducted as the test substance is an inorganic substance.
Adsorption/ desorption
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex VIII, section 9.3.1, the test on adsorption/desorption screening does not need to be conducted as the substance can be expected to have a low potential for adsorption based on the octanol water partition coefficient. The theoretical, calculated (EPIWIN) log Pow is 0.23, i.e. very low, as expected for an inorganic substance.
Just for additional information,a study was available to assess the adsorption/desorption properties of the analogue substance copper. Based on the results of this study and a read-across approach on the registered substance, copper dibromide can be regarded as a substance adsorbed on the soil, with log Kd median values considered to be between 4.65 and 4.76. Particulate organic carbon values given in the study allowed to calculate the koc.
In the conditions of the study, koc values are determined to be 539 440 L/kg (Tay Estuary) and 575 877 L/kg (Forth Estuary).
For CSA purpose, the most conservative value is used as the key koc value of the substance, i.e. 575 877 L/kg.
Additional information
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.
