Endpoint:
Henry's law constant
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Principles of method if other than guideline:
The Henry’s law constant (HLC) is directly calculated as a ratio of the vapour pressure to the water solubility
GLP compliance:
no
H:
0.001 Pa m³/mol
Temp.:
25 °C
Conclusions:
The Henry's Law Constant of the substance is calculated to be 0.00054 Pa m³/mol at a temperature of 25 °C
Executive summary:

The Henry's Law Constant of the substance is calculated to be 0.00054 Pa m³/mol at a temperature of 25 °C. It is directly calculated as a ratio of the vapour pressure (VP, 0.00628 Pa) to the water solubility (c, 4000 mg/l), which are both experimentally determined at 25 °C. The molecular weight (MW, 342.35 g/mol) of the test item was also used for estimation.(Currenta, 2010).

Description of key information

The Henry's Law Constant of 0.00054 Pa m³/mol at 25 °C for the substance  is directly calculated as a ratio of the vapour pressure to the water solubility (Currenta, 2010). According to the classification scheme of Thomas (1990), the substance is low  volatile from surface waters.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0.001
at the temperature of:
