- Executive summary:
Method
The melting point of the test substance was determined using the Differential Scanning Calorimetry (DSC) according to the OECD TGs 102 and 103, and the European Methods A.1 and A.2
Results
Between 56 - 250°C there are three negative peaks related to the loss of solvent. The test substance decomposes between 259 - 364°C (onset 275.8°C, enthalpy = 628.6 J/g)
Conclusion
The substance is a solid powder at 20°C and 101325 Pa.
