Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Freezing point:<-80°C (EU Method A.1)
Key value for chemical safety assessment
Additional information
A freezing point value of <-80°C was obtained for the submission substance using a method for the determination of freezing point in accordance with relevant test method and in compliance with GLP. The result is considered to be reliable. In addition to the method in determining the freezing point, thermal analysis was performed using DSC/TGA, endothermic peaks were observed from about 50 - 180°C. The endothermic effects were described by the study author as most likely due to a combination of evaporation and reaction and/or decomposition of the test substance. After the experiment, a yellow residue remained in the sample container.
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.
