Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Determination of the melting point.
Key value for chemical safety assessment
Additional information
The determination was carried out by differential scanning calorimetry, using a procedure designed to be compatible with Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
Instrument: Mettler Toledo DSC822e Differential Scanning Calorimeter (DSC) incorporating ThermoHaake Cooler EK45/MT.
Sample crucibles: Aluminum crucibles with lids.
Reference crucibles: Empty crucible with lid.
Test conditions: The test was performed in an air atmosphere.
Discussion
As a result of the low rate of enthalpy change during decomposition, the onset temperature can only be approximated.
The small endotherm at approximately 120 to 140°C was considered to be most likely due to volatilization of the entrained water impurity.
Conclusion
The test item has been determined to decompose from approximately 189 °C (462 K). As the test item decomposed, no value for melting temperature could be determined.
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.
