EC number: 615-206-1
CAS number: 709031-45-8
DSC EXPERIMENT 1
Endothermic peak between 175°C and 200°C (extrapolated onset
temperature: 194.505°C) directly followed by an exothermic effect
starting at 200°C. The endothermic effect was most likely obtained due
to melting of the test item. The exothermic effect was probably obtained
due to reaction and/or decomposition of the test item. After the
experiment, a dark brown molten residue remained in the sample container
(original colour: light tan).
DSC EXPERIMENT 2
In order to investigate the melting peak, Experiment 2 was stopped
directly after the endothermic peak. Extrapolated onset temperature:
194.545°C. After the experiment, a light yellow molten residue remained
in the sample container. The change of the colour indicated reaction
and/or decomposition 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 194.5°C. Reaction and/or
decomposition of the substance started during melting.
