Conclusions:
Melting range of the test substance = 169.59 - 196.53 °C (onset at 181.90 °C, enthalpy = - 77.3 J/g).
Massive decomposition of the test substance occurs from 310 °C onwards, before any boiling.
Executive summary:

The melting point of the test substance was investigated according to OECD guideline 102: Differential Scanning Calorimetry, DSC. The melting range was 169.59 - 196.53 °C (onset at 181.90 °C, enthalpy = -77.3 J/g). From 310 °C onwards, there is massive decomposition of the test substance before any boiling occurs.
