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 the test substance was measured by DSC between -90 °C and 100 °C with a heating / cooling rate of 10 K/min in 2 cycles. Three independent runs were performed. For the measurement a capsulated crucible was used. Under the study conditions, the test substance shows a melting area of crystalline subcomponents between 8 °C and 41 °C (Kintrup, 2017).

Description of key information

The melting point was determined according to OECD Guideline 102 and a method similar to EU Method A.1 (Kintrup, 2017).
