Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

Information from a QSAR model and a reliable secondary source are sufficiently consistent to conclude that dissociation is not a significant property of this substance under any conceivable environmental or biological conditions. This confirms expert assessment that indicates no dissociable groups within the molecule.
