Optical melting determination

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

Conclusions:
Melting point determination using differential scanning calorimeter indicates a value of: 112.64 °C
Executive summary:

Melting point determination using differential scanning calorimeter indicates a value of: 112.64 °C

Description of key information
