- other: Melting temperature
- Conclusions:
- A freezing point value of 13.9°C at 1013 hPa and a melting point value of 16.0°C at 1013 hPa was determined in a reliable study conducted according to an appropriate test protocol. It was not compliant with GLP.
Reference
Results
The DSC diagrams show a freezing temperature (onset exothermic peak) at 13.9 °C (287.1 K) and a melting temperature (onset endothermic peak) at 16.0 °C (289.2 K).
There was no indication of any discernible decomposition in the diagrams.
