Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 is a white powder, which decomposes at 153°C before boiling. It has a density of 1.72 g/cm3, with a predicted vapour pressure values in the range of 2.08E-6 to 3.68E-7 Pa at 25ºC, suggesting that the substance is not volatile. The substance was reported to be freely soluble in water with a predicted n-octanol/water partition coefficient (log Kow) in the range of -2.382 to -1.9761. The substance is non-flammable, and does not possess oxidizing or explosive properties. Although the substance is not thermally stable, it presents only a low thermal stability hazard. Given its calculated dissociation constant of 12.13, which represents dissociation of the neutral molecules to form ions, the substance is expected to exist virtually exclusively in neutral, unionised form throughout the environmentally relevant range of pH 5 to pH 9.
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.
