Decomposition:
yes
Decomp. temp.:
> 276 - < 323 °C

The substance shows a first exothermic effect betwenn 226 and 274 °C following by a second exothermic effect between 276 and 323 °C which correspond to the decomposition of the substance.

The onset is 308 °C with an enthalpy energy equal to 151.8 J/g.

Conclusions:
Decomposition of the substance at T > 276 °C.
Executive summary:

The substance shows a first exothermic effect betwenn 226 and 274 °C following by a second exothermic effect between 276 and 323 °C which correspond to the decomposition of the substance.

The onset is 308 °C with an enthalpy energy equal to 151.8 J/g.
