Executive summary:

Method

Differential Scanning  Calorimetry (DSC) according to the OECD Test Guidelines 102 and 103.

 

Results

Between 30 and 140 °C, there is release of water/ solvent, followed by a degradation between 213 and 373 °C, (onset at 244.1 °C, enthalpy = 178.3 J/g).

Conclusion

The test item is a solid at 1013 hPa and 20 °C.
