Description of key information
Two studies reported in the end-point study records on the boiling point. In the first study the susbtance boiled over the approximate range 302 to 498 ˚C (575 to 771 K), and in the second study boiling point is found to be >400 °C. Key value for chemical safety assessment is estimated as 400 °C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 400 °C
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.
