Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- > 121 - < 122 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- yes
- Decomp. temp.:
- ca. 252 °C

Applicant's summary and conclusion
- Conclusions:
- The melting point of the substance is between 121 and 122 °C
- Executive summary:
The meting point of the substance was determined by DSC. The endothermic peak between 120°C and 124°C is the main melting region. The product starts to decompose in the sealed vial at 252°C with a mean energy of 184 J/g.
