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 119 and 163 °C, there is a endothermic peak associated to the release of water/ solvent, followed by a degradation that begins at 320 °C; therefore boiling point is not recorded.

Conclusion

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