Description of key information

The melting point of sodium cyanate is determined to be 550°C. 

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
823.15 K

Additional information

Weight of evidence approach:

4 different handbooks show the same value for melting point. This value is thus regarded as reliable.
