Conclusions:
The mean melting point of the test item (obtained from two measurements) is -34.8°C ± 0.5 °C
Executive summary:

The determination of the melting point was performed with the Differential Scanning Calorimetry method according to recognized guidelines (OECD 102, EU Method A.1) and under GLP. No deviation from the guideline was observed during the study.

Before the determination of the melting point of the substance, the apparatus was checked with a reference substance. Based on the result obtained, the apparatus was considered as acceptable for use.

The mean melting point of the test item (obtained from two measurements) was -34.8°C ± 0.5 °C

Description of key information

 

The melting point of the test substance was determined in a study performed with the Differential Scanning Calorimetry method according to recognized guidelines (OECD 102, EU Method A.1) and under GLP. The mean melting point of the test item was -34.8°C ± 0.5 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-34.8 °C

Additional information

The melting point of the test item was determined in one GLP-compliant study performed in accordance with standard methods, without deviations. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint.
