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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
- decomposition >250°C, no melting point; OECD Guideline 102; RL1; GLP
- CRC handbook of chemistry and physics the melting point: 235°C.
Key value for chemical safety assessment
Additional information
In the GLP-compliant study conducted according to OECD guideline 102 the final DSC measurements were performed in the temperature range from 20 - 340 °C.
Two endothermic peaks could be observed (peak maxima: 109 °C/242 °C [first run] resp. 109 °C/ 240 °C [second run]). These two peaks correlate with maxima observed during the thermogravimetric measurement. Upon further heating the DSC-curve showed no more sharp peaks but the typical fluctuating course of decomposition. Thus, no melting point could be detected, the substance decomposes.
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.
