Description of key information

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-92 °C

Additional information


Melting point values of -89.5 °C to -92.55°C are reported in the literature. The original references were not available for review and no further information is available. The value of -92°C corresponds with the result of the most recent study, which was considered reliable.

In accordance with Column 2 of REACH Annex VII, the boiling point study (required in Section 7.2) does not need to be conducted below a lower limit of -20 °C. The existing data is sufficient to indicate a melting point well below this temperature.
