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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
The final DSC measurements were performed in the temperature range from 20 - 340 °C. To determine a possible boiling point more precisely a crucible lid with a hole of 50 µm diameter was used in the measurements. The small hole causes the generation of a defined atmosphere at constant pressure inside the crucible and allows measurements at near equilibrium conditions, thus preventing evaporation of the test material before reaching the boiling point.
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.
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.
