During cooling an exothermic peak was observed between -40°C and -10°C.
The effect was obtained due to crystallization of the test item. During heating, an endothermic peak between -50°C and 25°C was observed. Due to an irregular baseline, caused by the composition of the test item, no defined melting temperature could be determined.
In order to obtain a sharper melting peak a lower heating rate of 5°C/minute was applied in the Experiment 2. The melting peak was observed between -50°C and +10°C but peal shape was still broad. After the experiment, a colourless residue remained in the sample container.
The melting range was determined from the width of the peak obtained with experiment 2 (between -50°C and 10°C).
The melting range of MLA-3202 was determined to be -50 to +10°C (223 – 283K) by using DSC.
