- Remarks on result:
- other: In a DSC, ca. 40 to ca. 500 °C, according to OECD 113, a strong exothermic decomposition reaction is observed from 141 °C (closed metal vessel, V4A, heating rate 1 K/min), with a decomposition energy > 4450 J/g.
Sealed glass ampoule results:
| No. | Sample Mass in mg | Temperature Range in °C | Type of effect | Energy in J/g |
| 1 | 27.0 | approx. 40 - approx. 70 | endothermic | |
| 265 - > 500 | exothermic | > 2400 | ||
| 2 | 24.3 | approx. 40 - approx. 70 | endothermic | |
| 269 - > 500 | exothermic | > 2450 |
An exothermic effect was observed in the temperature range beginning at 265 °C. The exothermic reaction was not finished at the end of the measurement range at 500 °C. The decomposition energy is more than 2400 J/g.
Closed metal vessel (V4A-steel) results:
| No. | Sample Mass in mg | Temperature Range in °C | Type of effect | Energy in J/g |
| 1 | 103.6 | approx. 40 - approx. 70 | endothermic | |
| 141 - > 500 | exothermic | > 4450 |

Applicant's summary and conclusion
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.
