Reference
In duplicate definitive melting point determinations, the sample was observed to begin darkening at approximately 207°C, indicating decomposition. When heating was continued to 360°C in the preliminary test, the sample remained solid and became dark brown in appearance.
Description of key information
Decomposes above approximately 207°C without melting (OECD 102, EU A.1)
Key value for chemical safety assessment
Additional information
Melting / freezing point at 101 325 Pa: Not determinable; decomposes at temperatures above approximately 207°C without melting
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
