Description of key information
The freezing point was determined as being 1.0°C based on a Differential Calorimetry Scanning and visual assessment.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 1 °C
Additional information
Two studies are available on the freezing point. Both studies are reliable and were conducted according to current guidelines. The two studies yielded similar results (1.0°C on 98.55% purity material and -1.2°C on 96.85% purity material). The key study is considered to be the one conducted on the test substance of 98.55% purity.
