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).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
