The DSC-curves obtained during the two experiments are included in attachments. During the cooling in the first experiment, an exothermic peak between -30 °C and 15 °C was observed. The effect was obtained due to crystallization of the test item. During heating two endothermic peaks between -25 °C and 50 °C were observed. A first broad peak followed by a sharp second peak. The peak maximum of the first peak was 24.68 °C and its extrapolated onset temperature was 9.08°C. The peak maximum of the second peak was 35.99°C. It was assumed that the first peak was due to melting of the test item. The source of the second effect was unknown.

In order to investigate the peaks between -25 °C and 50 °C, a repeated heating cycle was applied in the second experiment. With the first heating, the peak maximum of the first peak was 23.92 °C and its extrapolated onset temperature was 9.29 °C. The peak maximum of the second peak was 35.23 °C. With the second heating, the first peak had a maximum of 24.07 °C and an extrapolated onset temperature was 18.68 °C. The second peak had a maximum of 33.08 °C.

Conclusions:

The melting point of MTDID 15670 was determined to be 24 °C by the EU Method A.1.

Executive summary:

The melting point of MTDID 15670 was tested using differential scanning calorimetry (DSC). The melting temperature was determined to be 24 °C. The study was conducted in accordance with EU Method A.1 and was GLP compliant; therefore the study is considered reliable without restrictions.
