Method
The test item melting point was determined using the Differential Scanning Calorimetry (DSC) according to the OECD Test Guidelines 102 and 103.
Results
Between 25 -110 °C, the imbibition water/solvent release was observed, followed by endothermic reaction between 126 -181 °C (onset 143.3 °C, enthalpy = -28.9 J/g). Between 207 - 244 °C (onset at 211 °C; enthalpy = 103.8 J/g) the substance decomposed.
Conclusion
The test item is solid at 1013 hPa and 20 °C- Endpoint:
