Key result
Melting / freezing pt.:
>= 22 - <= 65 °C

- The test substance showed a melting area of crystalline subcomponents between 22°C and 65°C in the 1st heating run (mean value from repeat determination; 1st melting from sub component).

22°C – 65°C (from first measurement)

22°C – 64°C (from second measurement)

22°C – 65°C (from third measurement)

- The cooling run showed a begin of crystallization at ca. 59°C. In the 2nd heating run, the test substance showed a melting although.

Conclusions:
Under the study conditions, the test substance showed a melting area of crystalline subcomponents between 22°C and 65°C.
Executive summary:

A study was conducted to determine the melting point of the test substance according to OECD Guideline 102 and similar to EU Method A.1. To determine the melting behaviour (three independent single measurements), the test substance was measured by Differential Scanning Calorimetry (DSC) between -90°C and 150°C with a heating / cooling rate of 10 K/min in 2 cycles. For the measurement, a capsulated crucible was used. Under the study conditions, the test substance showed a melting area of crystalline subcomponents between 22°C and 65°C (Kintrup, 2015).

Description of key information

The melting point was determined according to OECD Guideline 102 and similar to EU Method A.1 (Kintrup, 2015)
