Results and discussion

Melting / freezing point
Key result
Melting / freezing pt.:
> 25 °C

Any other information on results incl. tables

ln the temperature range between -150 and 25°C, no melting of the test substance was observed. This means that the test substance did not crystallize under the test conditions.
