Applicant's summary and conclusion

Conclusions:
The test item has no a melting point and decomposes before boiling
Executive summary:

A determination of the thermal stability of the test item by DSC (Differential Scanning Calorimetry) was performed with a DSC Mettler TOLEDO DSC 1, using a perforated crucible.

The substance has no melting point and starts decomposing at ca. 230°C.
