Applicant's summary and conclusion

Conclusions:
The substance decomposes at about 222 °C; no melting point was observed
Executive summary:

Differential Scanning Calorimetry (DSC) was performed with the substance in a sealed glass vial in air using a Mettler Toledo DSC 821e equipment. The heating range was from 25 to 450 °C with 3K/min. No melting was observed but only decomposition at about 222 °C.
