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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The normal boiling point is defined as the temperature at which vapour pressure of a liquid equals 101.325 kPa. If vapour pressure is 101.325 kPa or more at a given temperature, the substance is completely gaseous at that temperature. If this is the case at temperatures of 20 °C or over, the substance is a gas also according to the CLP Regulation (EC 1272/2008).
According to Column 2 of REACH Annex VII, a study to determine boiling point does not need to be conducted for substances which decompose before boiling at ambient pressure. A theoretical calculation estimated that the lowest boiling point of components of the test item was over 700 °C, however, this does not consider the earlier decomposition of the test item at lower temperatures which was observed during the DSC run. The test item began decomposing at 170 °C.
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.
