Additional information

A melting point value of -57.7°C is reported in two collections of reliable data. These results are considered to be reliable and the most recent is assigned as key study. The results given in several other secondary sources, to which a reliability could not be assigned, are in the range of -55 to -58°C and therefore support the key study result. Differences in the melting point may be due to impurites in the sample during testing.
