Applicant's summary and conclusion

Conclusions:
The melting point of the substance is 223 °C.
Executive summary:

The melting point of the substance was determined by differential scanning calorimetry with a Mettler Toledo, DSC 821e apparatus in a seales glass vial in air. The temperature range was from 25 °C to 450°V and the heating rate was 3 K/min. The melting point was found to be 223 °C.
