Table 1. Results

	First sample	Second sample
Sample weight	5.57 mg	4.23 mg
Pretreatment cooling down with	10 °C/min	1.25^°C/min
1.Scan glass transition of the liquid part	-23.6^°C	-23.5 °C
Melting point of the crystalline part	53.8 °C	53.9 °C
Quickly cool down with	320 °C/min	320.0 °C/min
2. Scan glass transition	-22.6 °C	-22.4 °C

 

Conclusions:

Freezing temperature (glass transition temperature of a liquid sample): -23 °C

Executive summary:

The study was performed to determine the freezing temperature of the substance according to the EU Method A.1 and in compliance with GLP. Using the differential scanning calorimetry method, the mean glass transition temperature, which is used as the melting temperature of the test substance was determined to be - 23 °C from the two determinations performed.
