Description of key information

No well-defined melting point could be measured.
In the close crucible an endothermic effect at approx. 165 °C to 179 °C was observed which could be interpreted as a beginning melting process. The exothermic process observed above this temperature can be assumed as decomposition of the test item.
In the open crucible an endothermic effect at approx. 135 °C to 157 °C was observed which could be interpreted as a beginning melting process. Above this temperature, the test item appears to decompose.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
157 °C
