Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

substance decomposes before boiling >370⁰C, EU Method A.2, McLean 2012

Key value for chemical safety assessment

Additional information

The boiling point of the substance was determined by differential scanning calorimetry according to EU Method A.2. A review of the thermograms that start at 50⁰C did not detect any endothermic events occurring between the 217⁰C melting point and the high temperature event starting at >370⁰C. Therefore it was concluded that the compound was decomposing before it boils, as determined by the presence of visible smoke and a black char-like residue observed on the sample vessel lid, a boiling point temperature could not be calculated. The extrapolated onset temperature, 409.17 ºC, is the temperature at which decomposition occurs.
