Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the melting point is above 300°C

Description of key information

In accordance with column 2 of REACH Regulation (EC) No 1907/2006 Annex VII section 7.5, the vapour pressure does not need to be conducted if the melting point is above 300 °C. Instead of melting the decomposition and/or sublimation starts above 747 °C (see IUCLID Section 4.2: Key.Melting point/freezing point.AQura.2010). Therefore, a study on vapour pressure is not required.

Key value for chemical safety assessment
