Applicant's summary and conclusion

Conclusions:
The test item was determined to decompose from approximately 120 °C (393 K). As the test item decomposed, no value for melting point could be determined.
Executive summary:

The test item was determined to decompose from approximately 120 °C (393 K), by differential scanning calorimetry and a metal block procedure, designed to be compatible with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. As the test item decomposed, no value for the melting point could be determined.
