Applicant's summary and conclusion

Conclusions:
The substance decomposes at about 190°C before melting.
Executive summary:

The melting point of the substance was determined by DSC using the the apparatus Mettler Toledo, DSC 821e in the temperature range 25 - 450°C and a heating rate of 3 K/min. The substance was in a sealed glass vial in air. No melting was observed but only a decomposition at about 190°C.
