Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

In the temperature range of 133 – 150 °C an endothermic effect (melting), was observed. Between approx. 189 – 280 °C a exothermic effect (decomposition) could be detected. During the heating phase an endothermic effect was observed in the temperature range of 133 – 150 °C, which can be assigned to the melting of the test item. The onset temperatures is 133.0 °C, the test item has a melting point of 133.0 °C.
Description of key information
133.5 °C at ca. 1013 hPa (capillary method). DSC method result (133 °C at ca. 1013 hPa) confirmed the value.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 133 °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.
