Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
ZAN 573 is a powdered pasty solid with a slight yellow color and mild odor. The size of the particles was analyzed to show that most of the aggomlerated particles were < 2000 μm, larger than particles which may be inhaled by workers. When the substance is intentionally dispersed with sunflower oil, the percentage of particles under 10 μm is less than 2%. The substance does not melt, but forms a transparent amber-colored mass when heated. It decomposes at temperatures over 320oC. It is not highly flammable and does not self-ignite. It does not have explosive or oxidizing properties. The relative density is 0.99 and the vapour pressure is low, 3.61 x 10-4Pa at 20oC. The substance is hydrolytically labile in water, and its water solubility cannot be determined. The partition coefficient is similarly difficult to determine, as the experimental result lies below the Kow value of the standards, suggesting that it is not highly soluble in lipid.
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.
