Description of key information

The melting/freezing point significantly varies with the grade of purity and the analytical method. Therefore the published datas spread around 
the "true" value.
The value range is 21-28°C. The value given here is the minimum value for solidification point which should be reached with material of a
purity of > 99.0 %.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
22 °C
