Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There is information available from a QSAR prediction to conclude that dissociation is not a significant property of this substance under any conceivable environmental or biological conditions. This agrees with a qualitative assessment of the molecular structure which suggests that there are no readily dissociable groups within the structure and the substance will not dissociate under any conceivable environmental conditions (taken as pH4 -9).
