Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance decompose at approximately at 250 °C
Key value for chemical safety assessment
Additional information
The determination of the melting temperature was based on the following guidelines: European Economic Community (EEC), EEC-Directive 92/69 EEC, Part A, Methods for the determination of physico-chemical properties, A.1 "Melting/Freezing temperature", EEC Publication No. L383, December 1992.
Organization for Economic Co-operation and Development (OECD), OECD guidelines for testing of Chemicals, guideline no. 102: "Melting point/Melting range”, July 27, 1995. Using a differential scanning calorimeter (DSC), both test substance and a reference were heated, using one single heat source. The difference between the heat flow to the sample and the heat flow to the reference was recorded.
Melting of the test substance was not observed. An exothermic effect which is probably caused by reaction or decomposition of the test substance was observed at temperatures above approximately 250°C (523 K). This does not imply that the test substance is stable up to this
temperature: it is very well possible that (slow) reaction or decomposition also occurs at lower temperatures and interferes with the process which causes the endothermic effect.
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.
