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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Direct Photolysis (air, water and soil):
The substance does not absorb light > 290 nm; direct photolysis will not occur;
Indirect Photolysis e.g. air:
The substance is a high melting solid with low vapour pressure and a low Henry`s Law Constant. Volatilisation is not an exposure route to be considered. Therefore this fate pathway need is not relevant.
Because of the solubility characteristic of the test substance in water, in organic solvents and in buffers, the determination of the abiotic degradation, i.e. determination of the hydrolysis rate as a function of the pH-value, according to guideline 92/69/EEC, appendix, C.7 was impossible. Pretest of the analogical Zn-salt and the corresponding acid of the substance of tests according OECD 111 at pH 4, 7 and 9 at 50°C indicate no hydrolysis (> 1 year)
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.
