Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Key result
- Relative self-ignition temperature:
- > 500 °C
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- During the DSC run up to 500°C no exothermic event could be observed. Therefore, the test item is no subject to the classification procedures for self-reactive substances and the acceptance procedures for Class 1 explosives need not to be applied according to UN-MTC.
Reference
During the DSC run no exothermic event could be observed. The test item remained visually unchanged after the test. Therefore, the test item is no subject to the classification procedures for self-reactive substances and the acceptance procedures for Class 1 explosives need not to be applied according to UN-MTC. From the DSC curve it can be derived that the test item has a melting point above 500 °C. The test item is stable up to 150 °C according to OECD 113. As the test item contains no chemical groups associated with explosive properties testing can be waived based on a consideration of the chemical structure in accordance with REACH Annex VII, column 2 of section 7.11. The negative result obtained in the screening test according UN-MTC support this conclusion as well.
Test item is no subject to the classification procedures for selfreactive substances and the acceptance procedures for Class 1 explosives need not to be applied according to UN-MTC. Furthermore, no endothermic transitions could observed in the range between room temperature and 519°C.
Description of key information
During the DSC run up to 519°C no exothermic event could be observed. Therefore, the test item is no subject to the classification procedures for self-reactive substances and the acceptance procedures for Class 1 explosives need not to be applied according to UN-MTC.
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.
