- Executive summary:
Method
The test was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis.
RESULT
Between 107 and 149 °C, there is a negative peak associated to the melting point, followed by a degradation starting from 220 °C.
Reference
Between 107 and 149 °C, an endothermic peak related to the melting point was observed, followed by a degradation starting from 220 °C.
Description of key information
There is a endothermic peak associated to the melting point between 107 and 149 °C (onset 125.77 °C), followed by a degradation starting from 220 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 125.77 °C
Additional information
The Melting Point analysis was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry (DSC) method for the analysis. Between 107 and 149 °C, there is an endothermic peak related to the melting point, followed by a degradation starting from 220 °C.
