Specific details on test material used for the study:
-Purity: Unknown or Variable composition, is a Complex reaction product, or a Biological material (UVCB)
-Description: Dark Green Liquid
-Storage: Room temerature (15 to 30°C)
Key result
Melting / freezing pt.:
< -20 °C
Remarks on result:
other: Freezing point
Key result
Melting / freezing pt.:
< -60 °C
Remarks on result:
other: Melting point
Conclusions:
The freezing point of the test substance was <-20°C. No endotherms characteristic of a melting temperature were recorded on either test, therefore the melting temperature is <-60°C. An exothermic reaction followed by an endothermic reaction; 126.06 to 238.05°C (test 1) and 118.16 to 237.33°C (test 2), mean 122 to 238°C. Decomposition was deemed to commence at 122°C. The onset temperatures of the thermograms were 190 and 216°C.
Executive summary:

The freezing point of the test substance was <-20°C. No endotherms characteristic of a melting temperature were recorded on either test, therefore the melting temperature is <-60°C. An exothermic reaction followed by an endothermic reaction; 126.06 to 238.05°C (test 1) and 118.16 to 237.33°C (test 2), mean 122 to 238°C. Decomposition was deemed to commence at 122°C. The onset temperatures of the thermograms were 190 and 216°C.
