- Executive summary:
Melting point determination using differential scanning calorimeter indicates a value of: 112.64 °C
Reference
Optical Melting determination: Range: 114.3-116.9°C. Point: 115.3 °C
The thermogram shows an endothermic phase transition from solid to liquid (lined peak). Onset result is more specifically related to the physically change -Melting Point since it is not influenced by sample size and scan rate.
Onset: 112.64°C Max Peak: 116.47 °C
Description of key information

Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 112.64 °C
