Flash point
Administrative data
- Endpoint:
- flash point of flammable liquids
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
The melting point of the substance was determined in DSC experiments to be 121.4°C, thus the substance is not a low melting point solid.

- Executive summary:
Differential Scanning Calorimetry (DSC) experiments were performed in a GLP study according to EC A.1, OECD 102 and OPPTS 830.7200.
The melting temperature of the substance was determined in duplicate obtaining a mean value of 121.4°C.
Reaction and/or decomposition of the substance was observed at temperatures > 275°C.
Two experiments were performed to investigate the melting (and boiling) behaviour of the substance.
DSC EXPERIMENT 1
An endothermic peak was observed between 100°C and 150°C followed by another endothermic effect starting at ca. 275°C. The extrapolated onset temperature of the peak was 121.715°C. This endothermic effect was most likely caused by melting of the test item. The second endothermic effect was probably due to reaction and/or decomposition of the test item.
After the experiment, a yellow molten residue remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test item. Based on this visual observation, it was concluded that the test item had molten and that the change of the colour demonstrated reaction and/or decomposition of the test item.
DSC EXPERIMENT 2
In order to investigate the melting peak, in Experiment 2 heating was stopped directly after the melting peak. The extrapolated onset temperature was 121.102°C.
After the experiment, a white molten residue remained in the sample container. It demonstrated that melting was the reason for the endothermic effect.
DATA HANDLING
The melting temperature was determined as the mean melting temperature of Experiment 1 (121.715°C) and Experiment 2 (121.102°C).
