Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
In a pre-test (one run from 25 to 400 °C, rate 20 °C/min) two endothermic heat effects were observed, the first peak starting at 137 °C the second at 330 °C. After the experiment, the sample had lost about 95.8% of its mass and stained the cup black. In the main test an endothermic heat effect was observed at 136 °C. During these runs, samples lost no weight and a colorless stringy drop remained.
Description of key information
136 °C (OECD 102, A.1), 133 °C and 133-135 °C (DIN 53181)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 136 °C

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.
