Key result
Melting / freezing pt.:
> 375.8 K
Atm. press.:
1 atm
Decomposition:
yes
Decomp. temp.:
375.8 K
Conclusions:
No melting for the substance was observed until 375.8 K. Decomposition occured at 375.8 K.
Executive summary:

The melting point of the test substance was investigated in a study conducted according to EU Method A.1, using Capillary method (liquid bath). Based on the findings of this study, no melting for the substance was observed until 375.8 K as decomposition occured above 375.8 K.
