Executive summary:

Method

The test item melting point was determined using the Differential Scanning Calorimetry (DSC) according to the OECD Guidelines 102 and 103.

Results

Water/imbibition solvent release was observed between 83 °C and 120 °C, followed by a little endothermic event between 188 °C and 294 °C (onset at 205.7 °C, enthalpy: -23.2 J/g) and then decomposition between 353 °C and 416 °C (onset at 356.8 °C, enthalpy: 42.7 J/g); therefore boiling point is not recorded.

At 20 °C and 1013 hPa, the substance is solid.
