Any other information on results incl. tables
DSC EXPERIMENT 1
Endothermic peak between 25°C and 75°C. The extrapolated onset temperature of the peak could not be determined since it was observed within 2 minutes from the start of the experiment. The endothermic effect was most likely obtained due to melting of the test item. The second endothermic effect (from 125°C) was probably obtained due to reaction and/or decomposition of the test item. After the experiment, an off white molten residue remained in the sample container.
DSC EXPERIMENT 2
In order to rule out degradation during melting, Experiment 2 was stopped directly after the melting peak. A small endothermic peak was observed between -25°C and 0°C; probably caused by restructuration of the test item. The extrapolated onset temperature of the second endothermic peak was 59.002°C. After the experiment, a colourless molten residue remained in the sample container (original colour: off-white to pale yellow). It demonstrated that melting was the reason for the endothermic effect at 59.002°C. The difference in residue colour compared to Experiment 1 indicated that reaction and/or decomposition caused the endothermic effect from 125°C on in Experiment 1.
DSC EXPERIMENT 3
The extrapolated onset of the melting peak was 58.532°C. After the experiment, a colourless molten residue remained in the sample container.
DATA HANDLING
The mean of Experiment 2 (59.002°C) and Experiment 3 (58.532°C) was reported as the melting point of the substance.
Applicant's summary and conclusion
- Conclusions:
- The melting temperature of the substance was determined to be 58.8°C.
- Executive summary:
Differential Scanning Calorimetry (DSC) experiments were performed in a GLP study according to EC A.1, OECD 102 and OPPTS 830.7200.
The melting temperature of the substance was determined in duplicate obtaining a mean value of 58.8°C. Reaction and/or decomposition of the substance was observed at temperatures from 125°C.
