Applicant's summary and conclusion

Conclusions:
The test item melts at 149.8°C at atmospheric pressure.
Executive summary:

The melting point of the test item was investigated in a study conducted according OECD Guideline 102 (Melting point / Melting Range; 1995) and EU Method A.1 (Melting / Freezing Temperature; 2008) using DSC and capillary measurements. Based on DSC measurements, the melting point was determined to be 149.8°C at atmospheric pressure (1003 hPa). The results of the DSC measurements were confirmed by the capillary method.
