Three independent experiments were conducted. The melting point of the test item was determined to be 103.7 °C in each single experiment.

Conclusions:
The melting point of the test item is 103.7 °C.
Executive summary:

The study was conducted according to Regulation (EC) No 440/2008 method A.1 to determine the melting point of the test item using the capillary method. At the start of the test at 99 °C the test item was an almost white, fine crystalline powder. The melting point of the test item was determined to be 103.7 °C.

Description of key information

The melting point of the test item is 103.7 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
