Description of key information

Henry's Law constant: 0.208 Pa m³/mole (HenryWin v3.20, Bond estimation method)

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0.208
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).
