Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Melting Point / Melting Range (DSC):


One measurement in an aluminium crucible with a hole showed an endothermic effect (melting) in the temperature range -10 °C to +15 °C with an onset temperature of -6.3 °C.The onset temperature is derived from the intersection of the tangent line with the highest slope of the endothermic peak with the baseline.



















Ident-No.
