Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The Henry’s law constant (HLC) is directly calculated as a ratio of the vapour pressure (VP, 0.0002 Pa, Fonseca, 2012) to the water solubility (c, < 0.15 mg/l, Neuland, 2012), which are both experimentally determined at 20 °C. The molecular weight (MW, 465.4 g/mol) of the substance was also used for estimation. The substance is low  volatile from surface waters.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0.621
at the temperature of:
20 °C
