Results and discussion

Any other information on results incl. tables

The definitive DTA curves resulted in one endothermic region and a broad exothermic region. The mean onset temperature, point of reaction, minimum/maximum temperature, offset temperature, and heat changes were as follows:

Endothermic Region

Onset Temperature (°C) - 208.4

Point of Reaction (°C) - 211.1

Min. Temperature (°C) - 213.1

Offset Temperature (°C) - 215.1

Heat Change (μVs/mg) - 9.3330

Exothermic Region

Onset Temperature (°C) - 215.8

Point of Reaction (°C) - 217.3

Max. Temperature (°C) - 328.5

Offset Temperature (°C) - 449.3

Heat Change (μVs/mg) - 14104.35

The endothermic region was indicative of a possible solid-to-liquid phase transition (melting point/range). The broad exothermic region was indicative of thermal decomposition and/or combustion of the test substance. The test substance was determined to be thermally stable below 208°C.

Applicant's summary and conclusion

Conclusions:
This study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability, repeatability).
The test substance was determined to be thermally stable below 208°C
Executive summary:

A simultaneous thermogravimetric analysis and differential thermal analysis (TGA/DTA) was performed on the test substance. The thermal analysis of the test substance resulted in one endothermic region with a mean onset temperature of 208.4°C and a broad exothermic region with a mean onset temperature of 215.8°C. The endothermic region was indicative of a possible solid-to-liquid phase transition (i.e. melting point/range), while the broad exothermic region was indicative of thermal decomposition and/or combustion of the test substance. The exothermic region resulted in a mean heat change of 14104.35 μVs/mg. The test substance was determined to be thermally stable below 208°C.
