- Conclusions:
- According to OECD Guideline 102 (1995) and Regulation (EC) No 440/2008 Method A.1., the substance has a melting point of 146.4 °C.
Reference
During the heating phase a distinct endothermic effect was observed in the temperature range of 140 – 160 °C, which can be associated with the melting of the test item. As the onset temperatures (146.39 and 146.49 °C) in both tests do not deviate more than 0.5 K from their mean value of 146.44 °C, this temperature can be used as melting point.
Description of key information
The substance has a melting point of 146.4 °C at atmospheric pressure (1004 hPa).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 146.4 °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.
