Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The melting point of potassium cyanate is 315 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
588 K

Additional information

Weight of evidence approach:

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