Materials and methods

Principles of method if other than guideline:
Calculated using EQUATION R.16-4 (Henry = (VP*MW)/Solubility) in the REACH guidance R.16. Measured input values were molecular weight (MW = 362.09 g/mole), vapour pressure (VP = 2.88 kPa or 2880 Pa) and water solubility (solubility = 0.15 mg/L).
GLP compliance:
no

Applicant's summary and conclusion

Conclusions:
The Henry's Law Constant is 6950000 Pa m³/mol. Calculated using EQUATION R.16-4 (Henry = (VP*MW)/Solubility) in the REACH guidance R.16.
Executive summary:

Henry's Law constant was calculated for the test substance using EQUATION R.16-4 (Henry = (VP*MW)/Solubility) in the REACH guidance R.16. Measured input values were molecular weight (MW = 362.09 g/mole), vapour pressure (VP = 2.88 kPa or 2880 Pa) and water solubility (solubility = 0.15 mg/L). The Henry’s Law constant was calculated as 6950000 Pa m3/mol at 20°C.
