Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 result
Decomp. temp.:
> 311 °C

The product starts to decompose in the sealed vial at 311 °C with a mean energy of 334 J/g.

The minor exothermic process in the 246 - 304°C region may lead to a pressure increase in closed systems, if it is due to a partial decomposition.

The test substance decomposed at >311°C.

Description of key information

Decomposed at >311°C without melting.

Key value for chemical safety assessment

Additional information


The determination was conducted by DSC with a heating rate of 3 K/min.
