Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Henry's law constant (H) (in Pa m³/mol):
at the temperature of:
25 °C

Additional information

No experimental studies are available determining the Henry’s Law constant (HLC) of the test substance. Therefore, the HLC was estimated using HenryWin v3.20 (EPI Suite v4.11). The bond-estimation method resulted in a HLC of 0.208 Pa m³/mole at 25 °C indicating that the test substance is of low volatility (OECD (2000): OECD Series on testing an assessment number 23: Guidance document on aquatic toxicity testing of difficult substances and mixtures).
