Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

not scientifically necessary

Key value for chemical safety assessment

Additional information

Based on the specific rules for adaptation from column 1 Annex VII of the REACH Regulation, the study does not need to be conducted since the substance decomposes before boiling (namely, rearrangement). In fact based on the DSC results reported in the melting point determination, the substance after melting changes its composition. The re-arrangment is confirmed by the IR spectra acquired before and after the thernal analysis showing different vibrations.
