Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No definite melting point between 25 and 450 °C 

Key value for chemical safety assessment

Additional information


EC Method A.1

No melting point could be observed after four determinations, twice in an open and twice in a closed crucible. A small endothermic effect could be observed between 60 and 80 °C which could not be reproduced by a second heating phase. The residues in the crucible were white and powdery. This leads to the assumption that the test item did not actually melt. Therefore an additional determination of the melting point by capillary method was performed.
