The colour of the test item changed in the course of the measurement from a white powder to a black residue. From this fact and considering the result of the DSC-measurement in a closed glass crucible it can be concluded that the test item boiled under decomposition in the temperature range of approximately 437 - 468 °C.

Conclusions:
The test item boiled under decomposition in the temperature range of approximately 437 - 468 °C.
Executive summary:

A study was conducted according to OECD TG 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry. The test item was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). Two tests with about 18 mg of the test item were performed. The crucible was heated from room temperature to 500 °C with 10 K/min heating rate. Two DSC-runs in aluminium crucibles with a hole showed an endothermic effect after melting in the temperature range 410 - 480 °C with an onset temperature of approx. 450 °C.
