EC number: 619-217-2
CAS number: 96487-85-3
TGA EXPERIMENT (PRELIMINARY TEST)
Significant decrease of weight from 300°C. 25% weight loss at
362°C and 70% weight loss at 445°C.
After the experiment, an orange molten residue remained in
the sample container (original colour: off-white). The change of the
colour indicated reaction and/or decomposition of the test item.
DSC EXPERIMENT 1
An endothermic peak between 150°C and 200°C was observed. The
extrapolated onset temperature of the peak was
183.226°C. The effect was most likely obtained due to melting of the
test item. An endothermic peak followed by an exothermic peak between
300°C and 362°C was observed. The effect was due to reaction and/or
decomposition of the test item. After the experiment, an orange molten
residue remained in the sample container.
DSC EXPERIMENT 2
Experiment 2 was performed to determine the duplicate melting
temperature of the test item.
extrapolated onset of the melting peak was 182.308°C. After the
experiment, an off-white molten residue remained in the sample
container. Based on visual observations, it can be concluded that the
endothermic peak was due to melting of the test item.
The melting temperature was determined as the mean extrapolated
onset temperature of Experiment 1 and Experiment 2.
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 182.8°C. During heating
from 25°C reaction and/or decomposition of the substance started at
