Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables

Two DSC measurements with a heating of 10 K/min showed an endothermal effect (melting) in the temperature range of 185 -205 °C. The onset temperature was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline. The first measurement showed also an exothermal effect after melting starting at approx. 340 °C.
