Applicant's summary and conclusion

Conclusions:

The melting point was determined in a GLP study according to EU method A.1 without deviations on the registered substance itself. Hence, there is no indication given that the results are not reliable. The test item shows no melting of crystalline subcomponents in a temperature range between -90 °C and 300 °C (at ambient temperature the test item is solid). The cooling run shows no crystallization. The 3rd heating run shows a second endothermic effect with an onset temperature of ca. 159 °C, which can be recognized as decomposition.

Executive summary:

The melting point was determined according to EU method A.1 in a study classified as Klimisch 1. The test item shows no melting of crystalline subcomponents in a temperature range between -90 °C and 300 °C (at ambient temperature the test item is solid). The cooling run shows no crystallization. The 3rd heating run shows a second endothermic effect with an onset temperature of ca. 159 °C, which can be recognized as decomposition.
