Melting point: <-20°C

Key value for chemical safety assessment

Additional information

In a reliable study conducted according to EU Method A.1 (Melting/Freezing Point) using Differential Scanning Calorimetry method, the sample was cooled between 25°C and -140°C; the substance did not melt but underwent a glass transition with an extrapolated onset temperature of ca. -118°C and a glass transition temperature of ca. -117°C. No other reliable studies are available, so this is considered the key result.

A pour point of ca. -35°C and a melting point of ca. -80°C were reported in secondary sources to which reliability could not be assigned.

The available data are considered sufficient to indicate that the melting/freezing point of the substance is below the threshold of -20°C specified in Column 2 of REACH Annex VII.
