Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

at the temperature of:
25 °C

Additional information

Based on REGULATION (EC) No 1907/2006, Annex VII, column 2 (section 7.5), the study on vapour pressure does not need to be conducted if the substance has a melting point > 300 °C. As the test substance decomposes at 255 °C, the study on vapour pressure shall be waived. The vapour pressure is necessary to calculate environmental concentrations and the given value is the lower bound of the potential range of values that can be chosen in the EUSES model.
