Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
The melting behaviour of the test item was estimated in a preliminary test with three replicate samples. Samples of the substance in a glass tube were heated from 30°C with a rate of 10°C/min until 400 °C.
The test item over 260 °C started to brown and by increasing the temperature the test item darkened, but stayed solid all over the measurement until 400 °C. None of the three replicates were melted.
Description of key information
The substance starts to decompose at 260 °C but remains solid up to the maximum temperature of 400 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 260 °C
Additional information
In a GLP study performed according to EU Method A.1 using the capillary tube method, a sample of the dried substance was heated at a rate of 10 °C from 30 °C up to a maximum of 400 °C. The substance started to decompose (browning) at 260 °C but remained solid up to 400 °C. The test was performed in triplicate.
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.
