Any other information on results incl. tables

No melting peak (endothermic reaction) in DSC was observed.

Between 200 °C and 540 °C the DSC showed exothermic peaks with different intensity, which indicated further decomposition of the test substance. A loss of mass began at about 290 °C. At 540 °C about 98 % of the initial mass was lost.
