Description of key information
Melting point: -126.5°C at 1013 hPa
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -126.5 °C
Additional information
A melting point value of -126.5°C at 1013 hPa was reported for the substance in a handbook or collection of reliable data to which the original sources are traceable. In other handbooks or collections of reliable date, melting point values of -128.1°C to -126.5°C were reported for the substance.
In available secondary sources to which reliability could not be assigned, melting point value of -133.9°C to -126°C were reported for the substance.
The available results are in agreement that the melting point of the substance is <-20°C.
