Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Executive summary:
A study was conducted to determine the thermal behaviour and stability of the test substance by DTA/DSC according to EC A.1 and OECD 102.
The sample was weighed in a crucible made of aluminium with perforated lid, placed in a DTA/DSC-system, cooled down to -80 °C and hold for 10 min. The sample was then heated up to 450 °C (heating rate 5 K/min). In comparison with an inert sample (empty crucible) the temperature difference and the heat effect was recorded. Any thermal effect corresponds to a baseline deviation.
Between -80 °C and approx. 200 °C no thermal effects could be observed. There is no indication for a melting point. At approx. 300 °C a steep endothermic signal was detected indicating a boiling point.
After the heating process a black-brownish residue remains in the crucible indicating decomposition of the test substance.
Reference
From -80 °C up to 450 °C the no indication of a melting point was detected but a steep endothermic signal at approx. 300 °C indicating a boiling point.
After the heating process a black-brownish residue remains in the crucible indicating decomposition of the test item.
Description of key information
A study was conducted to determine the thermal behaviour and stability of the test substance by DTA/DSC according to EC A.1 and OECD 102.
The sample was cooled down to -80 °C and then heated up to 450 °C.
From -80 °C up to 450 °C the test substance shows no melting point but a steep endothermic signal at approx. 300 °C indicating a boiling point. After the heating process a black-brownish residue remains in the crucible indicating decomposition of the test substance.
Key value for chemical safety assessment
Additional information
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.
