Description of key information

The Henry's Law Constant of the substance is calculated to be 0.0000146 Pa m³/mol at a temperature of 25 °C. It is directly calculated as a ratio of the calculated vapour pressure (VP, 2.19E-08 Pa) to the measured water solubility (c, 3 mg/l). The molecular weight (MW, 1998 g/mol) of the substance was also used for estimation. 

Key value for chemical safety assessment

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

Additional information

The substance is low  volatile from surface waters.
