Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Melting point: <-46°C (ASTM D2386)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -46 °C
Additional information
Two reliable measured data are available for the registered substance. A freezing temperature of <-46°C was determined for the substance using an appropriate ASTM test method, although full details are not available, the result is considered to be reliable. Also, a melting point in the range -44°C to -43°C (229.15 - 230.15 K) was determined for the substance using ISO 1392 test method.
In a secondary source to which reliability could not be assigned, a limit melting point of <0°C was reported for the substance.
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.
