Description of key information

770234 Pa*m3/mol indicates the test substance readily volatilizes from water and is unlikely to repartition to water.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
770 234

Additional information

A Henry's Law constant was calculated for the test substance from measured vapour pressure (2902.1 kPa) and solubility (520 mg/L) and molecular weight (138.0118 g/mol) using Equation R.16-4 (Henry = (VP*MW)/Solubility) in the REACH guidance R.16. This value indicates that the test substance would readily volatilize from water and is unlikely to repartition to water.
