- Executive summary:
A GLP-compliant melting study with FAT 40824/A was carried out according to OECD guideline 102 using thermal analysis method. The DSC-curve of the preliminary test (heating rate of 20 K/min from 25 °C to 400 °C). There was an endothermic heat effect observed starting at 80.8 °C. An exothermic reaction started at about 290 °C. After the experiment, the sample was dark in color and formed agglomerates, but was still powdery and lost about 24 % of its mass. In main test, An endothermic reaction could be observed between about 73 °C and 224 °C, followed by an exothermic heat effect starting at about 290 °C. After the experiment, the sample had lost about 24 % of its mass and the sample was a black colored powder forming agglomerates. Based on the study results, the melting point of the test material was determined to be >400 °C.

PRELIMINARY TEST
The DSC-curve of the preliminary test (heating rate of 20 K/min from 25 °C to 400 °C). There was an endothermic heat effect observed starting at 80.8 °C. An exothermic reaction started at about 290 °C. After the experiment, the sample was dark in color and formed agglomerates, but was still powdery and lost about 24 % of its mass.
MAIN TESTS
In order to determine the endothermic reaction more precisely, a first main test run was performed in the immediate vicinity of the peak temperature with the temperature rise adjusted to 10 K/min. 6.85 mg test item were heated up from 25 °C to 270 °C. A not well defined endothermic reaction started at about 61 °C. This heat effect was not due to melting since the test item was still a powder after the experiment. Further evaluation is beyond the scope of the study. To confirm the result obtained in the first main test, a second run was performed. A test item amount of 13.16 mg was heated up from 25 °C to 400 °C at a rate of 10 K/min. An endothermic reaction could be observed between about 73 °C and 224 °C, followed by an exothermic heat effect starting at about 290 °C. After the experiment, the sample had lost about 24 % of its mass and the sample was a black colored powder forming agglomerates.
Description of key information
