EC number: 947-652-0
CAS number: 943986-70-7
TGA EXPERIMENT (PRELIMINARY TEST)
Decrease of weight from 275°C upwards: 25% at 321°C.
After the experiment, a dark yellow/orange molten residue remained in
the sample container.
The change of the colour indicated reaction and/or decomposition of the
DSC EXPERIMENT 1
Two endothermic effects were observed between 50°C and 100°C followed by
an endothermic effect starting at ca. 250°C.
The temperature at maximum of the first effect was 77.207°C and the
temperature at maximum of the second effect was 79.235°C.
The endothermic effects were most likely caused by melting of the test
The third endothermic effect was probably caused by early stages of
decomposition reactions of the test item.
After the experiment, a molten residue that lost its colour remained in
the sample container.
DSC EXPERIMENT 2
In order to investigate the endothermic effects, in Experiment 2 heating
was stopped directly after the melting effects.
The peak max temperature at maximum of the first effect was 79.665°C and
the temperature at maximum of the second effect was 81.940°C.
After the experiment, a white molten residue remained in the sample
container (original colour: off-white).
It demonstrated that melting was the reason for the endothermic effects.
As the melting temperature of the test item could not be determined
accurately due to the two effects observed,
the melting temperature is reported as a melting range from 77.2°C to
Differential Scanning Calorimetry was performed to determine the melting
and boiling temperature. The experiments were based on EC A.1, OECD 102
and OPPTS 830.7200 (melting temperature) and on EC A.2, OECD TG 103 and
OPPTS 830.722 (boiling temperature). GLP-study.
The melting range of the substance was determined to be 77.2 - 81.9°C.
Reaction and/or decomposition of the substance occurs from 250°C upwards.
Boiling of the substance was not observed below the temperature at which
reaction and/or decomposition started.
