STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: ambient temperature
Key result
Melting / freezing pt.:
ca. -100 - ca. -71 °C
Decomposition:
no
Sublimation:

The test item had a significantly broadened melting peak with a maximum at- 75 °C, ranging from about -100 to -71 °C.

determination initial temperature [°C]  peak temperature [°C]  end temperature [°C]
 Test 1 ~ -100 -74.2  -70.5 
Test 2  ~ -100 -73.9 -69.3
Test 3  ~ -100 -75.5 -71.8
A   ~ -100   -75.3 -71.1
 B   ~ -100  -75 .1 -71.6
 mean value   ~ -100 -75 -71

The estimated accuracy is ± 1 °C.

TG/DSC-Test (non-GLP) was run up to 600 °C. An endothermic peak starting at about 150 °C with a total weight loss at about 300 °C showed the vaporization of the test item.
