- STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
-Storage conditions: Room temperature. - Key result
- Melting / freezing pt.:
- 184.2 °C
- Remarks on result:
- other: At about 183 °C slight bubble-formation could be seen and the test item began to turn brown, suggesting degradation at approximately the same temperature as the melting point.
- Conclusions:
- Under the conditions of this study, the melting point of the test material was found to be 184.2 ± 0.08 °C, with slight bubble-formation and colouration suggesting degradation at approximately the same temperature as the melting point.
- Executive summary:
The melting point of the test material was determined in accordance with the standardised guidelines OECD 102 and EU Method A.1 under GLP conditions using the capillary method.
A small amount of the test material was heated in the electronic controlled sample block and the temperature around the sample was displayed. The sample was observed visually whilst raising the temperature. The initial and final melting temperatures were determined.
Using a linear heating rate of 0.5 °C/min the melting point of the test material was found to be 184.2 ± 0.08 °C (95 % confidence interval), i.e. 457.3 K with slight bubble-formation and colouration suggesting degradation at approximately the same temperature as the melting point.
Under the conditions of this study, the melting point of the test material was found to be 184.2 ± 0.08 °C.

Description of key information
Under the conditions of this study, the melting point of the test material was found to be 184.2 ± 0.08 °C with slight bubble-formation and colouration suggesting degradation at approximately the same temperature as the melting point.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 184.2 °C
Additional information
The melting point of the test material was determined in accordance with the standardised guidelines OECD 102 and EU Method A.1 under GLP conditions using the capillary method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
A small amount of the test material was heated in the electronic controlled sample block and the temperature around the sample was displayed. The sample was observed visually whilst raising the temperature. The initial and final melting temperatures were determined.
Using a linear heating rate of 0.5 °C/min the melting point of the test material was found to be 184.2 ± 0.08 °C (95 % confidence interval), i.e. 457.3 K with slight bubble-formation and colouration suggesting degradation at approximately the same temperature as the melting point.
Under the conditions of this study, the melting point of the test material was found to be 184.2 ± 0.08 °C.
