Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The melting point for FC-72 is < -86 °C.
Key value for chemical safety assessment
Additional information
In the key study, warming curves were used to determine a melting point range of -87.1 to -86.05 °C for perfluoro-n-hexane and a glass transition temperature range of -140 to -136 °C for perfluoro-2-methylpentane. The procedure was documented. However, the study was not conducted in accord with GLP guidelines; therefore, the results are considered reliable with restrictions. The data included in the report was for the purified isomers rather than for FC-72 itself.
The company data sheet reports a pour point for FC-72 of -90°C; this value is included in a table of physicochemical properties only and cannot be assessed as to reliability.
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.
