In the preliminary test, the weight of the sample decreased significantly at 375°C. After the experiment, a brown/black molten residue remained in the sample container (original colour: off-white). The change of colour indicated reaction and/or decomposition of the test item.
In the DSC experiments, endothermic peaks have been observed between 200°C and 225°C. The extrapolated temperatures of the peaks were 215.6°C and 215.5°C (respectively in assay 1 and 2). In the second assay, the experiment was stopped directly after the melting peak. After the experiment, an off-white molten residue remained in the sample container. It demonstrated that melting was the reason for the endotermic effet.
The melting point of the test item was determined with the differential scanning method according to recognised guidelines and in compliance with GLP (Brekelmans, 2018). No deviation from the guideline was observed in the study.
The melting point was determined in two assays. The test item melts at 215.5°C.
The melting point of the test item was detemined in a key study of Klimisch validity 1 performed according to recognised guidelines and in compliance with GLP (Brekelmans, 2018).
No deviation from the guideline was observed in the study.
