Conclusions:
The melting point of the test substance was determined to be 66.0 °C
Executive summary:

A study was conducted according to OECD test guideline 102, Regulation (EC) No 440/2008 method A.1 to determine the melting point of the test item using capillary method. A small amount of the test item was crushed in an agate friction bowl and filled into three melting point determination tubes. The melting point was determined with a heating rate of 0.5°C/min. The melting point of the test substance was determined to be 66.0 °C

Description of key information

The melting point of the test substance was determined to be 66.0 °C (reference 4.2 -1).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
66 °C
