TGA EXPERIMENT (PRELIMINARY TEST)

Significant decrease of weight from 175°C. 25% weight loss at 215°C and 70% weight loss at 235°C.

After the experiment, a colourless residue remained in the sample container (original colour: colourless).

DSC EXPERIMENT 1

During cooling, an exothermic peak between -40°C and -20°C was found. The effect was obtained due to crystallization of the test item. During heating, an endothermic peak was observed between -50°C and 0°C. The extrapolated onset temperature of the peak was -19.027°C. The endothermic effect was due to melting of the test item. An endothermic peak was observed starting at 150°C. The endothermic effect was most likely obtained due to reaction and/or decomposition of the test item. After the experiment, a colourless residue remained in the sample container.

DSC EXPERIMENT 2

Experiment 2 was performed to determine the duplicate melting temperature. The extrapolated onset of the melting peak was -19.153°C. After the experiment, the sample appeared to have been unchanged, i.e. no decomposition and/or evaporation were observed. 

DATA HANDLING

The melting temperature was determined as the mean extrapolated onset temperature of Experiment 1 and Experiment 2.

Applicant's summary and conclusion

Conclusions:

The melting temperature of the substance was determined to be -19.1°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 -19.1°C.
