Description of key information

Melting point according to CRC Handbook of Chemistry and Physics, 90th Edition is -31.6°C
Melting point according to The Merck Index, 14th Edition is -38.6°C
Melting point according to EPISuite v4.0 - MPBPVP v1.43 calculation is -27.45°C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-31.6 °C

Additional information

Three pieces of data have been provided for melting point which are broadly similar. Hence a weight of evidence approach is considered justified.

The CRC Handbook data has been selected as key on the basis that it is close to a mean of the three values.
