- Executive summary:
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 43 and 196 °C, there is a negative peak associated to the release of water/ solvent, followed by a degradation between 276 and 413 °C; therefore melting points is not recorded.
Conclusion
The test item is solid at 1013 hPa and 20 °C
