Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Freezing point of test chemical was determined with Freezing Temperature Method and it was determine to be less than -16.39 °C at 978.0 hPa

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-16.39 °C

Additional information

The Freezing point of test chemical was determined with Freezing Temperature Method and it was determine to be less than -16.39 °C at 978.0 hPa

Other supporting studies from authoritative database and handbooks also suggest that the freezing point of test chemical was determined to be in the range of -20 degree C to -16.5 degree C.

Also, From EPI suit estimation software, freezing point of test substance was estimated to be -15.14 °C.
