Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Range: -24.0 to -24.3 °C 

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-24.1 °C

Additional information

A melting point value of -24.1°C is nominated as the key study (Budavari 1996) among the other secondary sources. This peer-reviewed chemical handbook is considered as a reliable source reference in which the original data sources are traceable.

The original reports for the other sources (Kronos 1992, NRPFPA 1994, Millennium 2007) were not available for review and no further information is available. The reliabilities of these results are not assignable.

None of the studies has recorded the pressure at which the melting point was measured. Nonetheless normal conditions were assumed.
