Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Measurements were performed using DSC according to OECD 102 and in accordance with GLP. 

Key value for chemical safety assessment

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

Additional information

Key value was determined using DSC according to OECD 102 and in accordance with GLP. The substance does not melt up to 400 deg. C. An endothermic peak between 75°C and 175°C was observed. The extrapolated onset temperature of the peak was 95.40°C. The effect was most likely obtained due to evaporation of water (test substance had a clay like appearance). After the experiment, the test substance was dryer than the original sample.
