Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The melting point was determined according to the OECD Guidelines for the Testing of Chemicals no. 102: "Melting Point / Melting Range" (July 27, 1995). The melting point was determined to be higher than 400°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
400 °C

Additional information

The test substance was tested in triplicate melting point capillary tubes using a temperature gradient of 30°C - 400°C at a rate of 10°C/min. No change of colour or melt was observed. A melting point of >400°C was reported.
