Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The substance, a metal complex, is a dark blue solid at 20 °C and 1013 hPa. Using the laser light scattering method, the mass median diameter value for its particles was found to be 23.77 µm.
The evaluation of thermal properties was based on a DSC analysis: a melting point and a boiling point were not detected; above about 250 °C an exothermic effect was observed.
The density was determined by using the gas comparison method. A relative density of 1.552 at 20 °C
was found.
The substance is very soluble in water at room temperature: the water solubility was estimated to be 40.6 g/l at 20 °C
The partition coefficient (n-octanol/water) of test item was estimated to be < 1.82 * 10^-6, using the estimation method (log Pow < -5.7).
No reactions with water or emission of flammable gases have ever been noted. Furthermore, for soluble dyes a reaction with water is not a desirable property from the use point of view. Therefore, the substance is not expected as a substance that in contact with water may react emitting flammable gases.
Even if the melting point is above 250 °C, an estimation of the vapour pressure of the test substance showed a value of
even lower than 3.5 * 10^-34 Pa at 25 °C.
The surface tension of a solution of test substance in water is not a desired property.
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.
