Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Henry’s Law Constant was calculated manually (Chemservice, 2014) and by the software tool EPIWIN/HENRYWIN v3.20 (Chemservice, 2014). The manual calculation according to ECHA REACH Guidance on information requirements and chemical safety assessment (Chapter R.16 - Environmental Exposure Estimation; version 2.1; October 2012) is considered as more reliable since substance specific properties (VP, WS) were taken into account. Conclusively, Henry's Law Constant amounts to 2.97 E-10 Pa*m3*mol-1at 20 °C.

The software tool HENRYWIN calculated a Henry´s Law Constant of 2.369 E-13 Pa*m3*mol-1 (25 °C) for the substance which is considered as supporting information. Both calculation methods determine a negligible Henry's Law Constant.
