Applicant's summary and conclusion

Conclusions:
The melting point of the substance is between 121 and 122 °C
Executive summary:

The meting point of the substance was determined by DSC. The endothermic peak between 120°C and 124°C is the main melting region. The product starts to decompose in the sealed vial at 252°C with a mean energy of 184 J/g.
