Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test substance decomposes before boiling.
Key value for chemical safety assessment
Additional information
The boiling point of the test substance was determined according to OECD Guideline 102 by differential thermal analysis (DTA) and thermogravimetric analysis (TGA). The thermal analysis of the test substance was performed using a TGA/DTA instrument with a temperature program at a rate of 5 °C/min from 50 °C to 500 °C.
On the DTA thermograms obtained from the thermal analysis in nitrogen under reduced pressure (3.13 - 3.33 kPa), no clear endothermic peak with weight loss, which could be assigned to the boiling point, was observed. Two endothermic peaks and two or three exothermic peaks with weight loss, which were assigned to the complex effects of vaporization and decomposition of the test sample, were observed above approximately 250 °C on the DTA thermograms. On the visual observation, colors of the sample container inner walls had changed to the black, suggesting the decomposition of the test substance.
On the DTA thermograms obtained from the thermal analysis in nitrogen under atmospheric pressure, no endothermic peak with weight loss, which could be assigned to the boiling point, was observed. Therefore, it was confirmed that the test substance thermally decomposed before reaching the intrinsic boiling point under both atmospheric and reduced pressure.
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.
