Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No boiling point determined (decomposition at 290 °C), OECD 103 and EU Method A.2, Fox (2015a)
Key value for chemical safety assessment
Additional information
The boiling point of the test material was investigated under GLP conditions and in accordance with the standardised guidelines OECD 103 and EU Method A.2, using a differential scanning calorimeter. All methodology and results were reported in full. The study was therefore assigned a reliability score of 1 in accordance with the principles for assessing data quality as described by Klimisch et al. (1997).
Aliquots of test material were placed in pierced aluminium crucibles and were heated up from 20 to 400 °C at 20 °C/min. The appearance of the samples (residue) and its weight loss were recorded after the test.
After being heated to 400 °C, the residue had lost approximately 61 and 57 % of its original weight for Determinations 1 and 2, respectively.
The test material has been determined to decompose from approximately 290 °C (563 K) at 101 kPa. As the test material decomposed, no value for boiling temperature could be determined.
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.
