CAS number: 75627-12-2
TGA EXPERIMENT (PRELIMINARY TEST)
Significant decrease of weight from 275°C upwards. At
549°C the sample weight had decreased by 16%.
After the experiment, a black charred residue
remained in the sample container (original colour: pink). The change of
the colour indicated reaction and/or decomposition of the test item.
DSC curve: see Figure 1 in the attached study report.
The DSC-curve obtained showed an exothermic peak between 25°C and
150°C. Based on the weight loss observed in the TGA experiment it was
assumed that this effect was most likely due to evaporation of
solvent impurities. From 175°C several effects were observed which are
related to reaction and/or decomposition of the test item. After the
experiment, a black charred residue remained in the sample container.
Differential Scanning Calorimetry (DSC) experiments were performed in a
GLP study according to EC A.1, OECD 102 and OPPTS 830.7200. The
substance has no melting temperature. During heating from 25°C to
400°C reaction and/or decomposition of the substance started at 175°C. Melting
of the test item was not observed below the temperature at which
reaction and/or decomposition started.
