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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
DSC-measurement: Boiling point
One endothermic effect was detected in the temperature range of 40-60 °C. Two exothermic effects were observed in the temperature range of 150-220 °C and in the temperature range of 330-400 °C.

DSC-measurement: Thermal stability
One endothermic effect was detected in the temperature range of 40-60 °C. Two exothermic effects were observed in the temperature range of 140-240 °C and in the temperature range of 300-470 °C. A third exothermic effect was detected in the temperature range of 470-500 °C.
After the measurement the test item’s appearance was black.

As the endothermic effect is observed in the perforated and closed crucible it can be assigned to the melting of the test item. No other endothermic effect is detected until the end of the measurement. Instead, the exothermic effects can be assigned to decomposition processes.
Final Results
The test item has no boiling point up to its decomposition at 140-150 °C as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995) and OECD Guideline 113 (1981).
Description of key information
The test item decomposes at 140-150 °C. After the measurement the test item’s appearance is black.

Justification for classification or non-classification
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.
