Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
-4.5 °C at 1013.25 hPa
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -4.5 °C
Additional information
A literature review was conducted. In a weight of evidence approach the literature values were evaluated. Brown and Green,1940 (as cited in REAXYS, 2014A) reports the melting point to be -4.5 °C at 1013.25 hPa. Furthermore Knother et al. 2009 (as cited in REAXYS, 2014B) reports the melting point to be -5.08 °C at 1013.25 hPa and the Hawley's Condensed Chemical Dictionary 15th Edition (as cited in HSDB, 2014) reports the melting point to be -4.5 °C at 1013.25 hPa. Three independent literature sources report the melting point in the same range. Thus, a melting point of -4.5 °C was chosen as key value for chemical safety assessment as it was from the most reliable literature source.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
