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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is inorganic
- Justification for type of information:
- In accordance with column 2 of REACH Regulation 1907/2006/EC Annex VII section 7.8, the test on partition coefficient n-octanol/water does not need to be conducted if the substance is inorganic. Copper dibromide is an inorganic substance, therefore this endpoint was waived.

Description of key information
In accordance with column 2 of REACH Regulation 1907/2006/EC Annex VII section 7.8, the test on partition coefficient n-octanol/water does not need to be conducted if the substance is inorganic. Copper dibromide is an inorganic substance, therefore this endpoint was waived.
Key value for chemical safety assessment
Additional information
For information, the theoretical calculated (EPIWIN) log Pow is 0.23, i.e. very low, as expected for an inorganic substance.
Nevertheless, this value is just given as information because the prediction is outside of the applicability domain of the model since very few inorganic compounds were included in the training data set for the methodology utilized in KOWWIN v 1.68 from EPISuite software.
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.
