Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In accordance with column 2 of REACH Annex VII, the study does not need to be conducted because the substance is a solid with melting point above 300°C (estimated). The DSC record of the sample does not show any endothermic signal attributable to a change of state, like melting point is.The TGA analysis does not show independent loss on weight processes (but a constant loss along the thermogram) it is not possible to unequivocally assign every thermal phenomenon to a decomposition process. The melting point indicated in the key value for chemical safety assessment has been estimated by Epiwin.

To estimate the exposure to the environment, the vapour pressure is a value required by EUSES 2.1. The value used has been estimated with EPI Suite: Epi Suite calculation: VP (Pa, 25 deg C) : 2.1E-031 (Modified Grain method). However, the boundaries of EUSES model for vapour pressure are 0.000001Pa-1000000 Pa, therefore the minimum value has been chosen for exposure estimation.
