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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The solubilites at 20°C were found as follows:
< 0.1 mg/L at pH 6.5 with loading rate of 0.1 g/L and 1.0 g/L
Key value for chemical safety assessment
Additional information
The determination was carried out by flask method according to OECD Guideline 105 and analyzed by UV/VIS spectroscopy.
The test item is a complex mixture. In addition to the determination via UV/VIS spectroscopy, the water solubility was therefore also investigated via determination of dissolved amounts of cobalt, nitrogen and carbon, the main elements contained in the test item.
Different sample weights were applied (each about 0.1 g/L and 1.0 g/L) to investigate whether fractions of different solubility are existent (partial solubility).
As result for the water solubility of the test item the values of the determination via UV/VIS spectroscopy can be preferably considered, because with this method the orange colored compound were measured, this method is the most sensitive of the methods applied and because the determinations via the elements confirm these results.
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.
