Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 <-20°C expected from analogue.
No further testing necessary.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-42.5 °C

Additional information

No data is available on the substance itself. Experimental freezing point was measured at -42.5°C on an analogue (choride salt). In accordance with column 2 of REACh Annex VII, the study does not need to be conducted below a lower limit of -20°C, and the margin of safety is supposed sufficient for purpose. Therefore the read-across is considered suitable for CLP and risk assessment purposes.
