Description of key information
Melting point: from -55°C to -50°C (from 218.15 to 223.15 K), at atmospheric pressure.
Key values used in a weight of evidence approach have been selected in previous Risk Assessment Report, 2008.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -50 °C
Additional information
Three values have been cited in various review articles and handbooks.
Data selected for a weight of evidence approach: -50 °C and - 55°C (data from reference handbooks according to R7 guidance document).
Data from supportive study: -47°C; Data from supportive study: -47°C (data cited in a review article without more details on method or origin, therefore considered as a supportive data but will not be inclueded in the weight of evidence approach.)
