Executive summary:

A study was conducted to determine the melting point of the test substance using differential scanning calorimetry (DSC). A sample of 10 mg test substance was loaded in a standard aluminum crucible (40 µL) fitted with a pierced lid. The measurements were conducted at a linear heating rate of 10°C per min using commercial DSC equimpment (Mettler DSC823e or Q10 from TA Instruments). The DSC cell was flushed with nitrogen gas at a flow rate of 50 mL per min. Under the study conditions, the test substance showed melting point at 231°C (Bruggemans, 2017).

Description of key information

The melting point was determined by differential scanning calorimetry (Bruggemans, 2017).
