Description of key information

Melting point: <-46°C (ASTM D2386)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-46 °C

Additional information

Two reliable measured data are available for the registered substance. A freezing temperature of <-46°C was determined for the substance using an appropriate ASTM test method, although full details are not available, the result is considered to be reliable. Also, a melting point in the range -44°C to -43°C (229.15 - 230.15 K) was determined for the substance using ISO 1392 test method.

In a secondary source to which reliability could not be assigned, a limit melting point of <0°C was reported for the substance.
