Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

A number of values are available for the melting point. The data indicates that it can be reliably concluded that the melting point is below -70C (<203K) and it can be concluded that the substance remains liquid at any conceivable low environmental temperature extreme. The QSAR methods do not seem accurate for this substance.
