Description of key information

The information is taken from a peer-reviewed handbook (Ullmann's Encyclopedia of Industrial Chemistry)

and two collections of data (American Cyanamid Company, Degussa).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
210 °C

Additional information

There are three different data sources available. At least one of the handbooks / collection of data is a peer-reviewed data source (Ullmann's Encyclopedia of Industrial Chemistry). The values for the melting point of dicyandiamid of all three data sources are between 208 -212°C (The mean value is used as key value for chemical safety assessment).
