Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 105 °C
Additional information
A similar value is reported in several peer-reviewed handbooks. These handbooks were grouped in only one endpoint study record which was flagged as a key study.
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.
