Reference
Preliminary test
A preliminary test was performed in the heating range from 25°C to 400°C with a heating rate of 20K/min. The first endothermic heat effect, the melting, was observed at 123.3°C.
Main test (two main test runs)
In order to determine the melting more precisely, further DSC-runs were recorded between 90°C and 170°C with a heating rate of 5 K/min. In the first main test run, the melting of T002251 was determined at 123.6°C. The melting of the test item during the second main test run was determined to be 123.5°C. During these runs, the samples lost 3% and 1.4% of their mass, respectively. After measurement both samples were melted and brownish black in color.
Description of key information
The melting point of T002251 was determined to be 123.4°C in a GLP study according to OECD guideline 102 and EU method A.1 (K1, Tognucci, 2003).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 123.4 °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.
