guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

Deviations:

no

GLP compliance:

yes

Type of method:

thermal analysis

Remarks:

Differential Scanning Calorimetry (DSC)

Melting / freezing pt.:

> 400 °C

Atm. press.:

ca. 1 013 hPa

Decomposition:

yes

Decomp. temp.:

>= 100 - <= 340 °C

Remarks on result:

other: No melting point in the temperature range of 25-400 °C was observed. Exothermic decomposition was observed in the range of 100-340 °C.

Conclusions:

Under the test conditions, the test substance shows no melting point in the temperature range of 25-400 °C only an exothermic decomposition beginning at 100 °C.

Executive summary:

The melting point/range of the test substance was determined in accordance with the EU Method A.1. in compliance with GLP.

The test performed by using DSC, Mettler-Toledo TA8000, in a closed glass pan.

Two measurements in a closed glass pan does not show any endothermic effect prior an exothermal decomposition was observed in the range 100-340 °C, with a decomposition energy of 691 J/g respectively 636 J/g.

Under the test conditions, the test substance shows no melting point in the temperature range of 25-400 °C only an exothermic decomposition beginning at 100 °C.
