- Specific details on test material used for the study:
- Clear, colourless liquid
Purity: 97.2% - Remarks on result:
- not determinable
- Remarks:
- No melting point was determined. A glass transition of the test item was observed at -78.8°C (194.4K).
- Conclusions:
- No melting point was determined. A glass transition of the test item was observed at -78.8°C (194.4K).
- Executive summary:
No melting point was determined. A glass transition of the test item was observed at -78.8°C (194.4K).
Reference
Reaction and/or decomposition of the test item was observed during the two DSC experiments at temperatures of > 175°C (> 448K). After the experiments, a brown residue remained in the sample container (original colour: colourless). The change of the colour indicated reaction and/or decomposition of the test item. The glass transition temperature was determined as the mean inflection point temperature of Experiment 1 (-78.643°C) and Experiment 2 (-78.859°C).
Description of key information
No melting point was determined. A glass transition of the test item was observed at -78.8°C (194.4K).
Key value for chemical safety assessment
