Description of key information

Henry's Law constant is required for exposure assessment and derivation of PNECsoil. It has been estimated from Molecular weight (Mwt; 210 g/mol), water solubility (S; 0.67 mg/l at 20'C) and vapour pressure (VP; 0.3112 Pa at 20'C) using the relationship: H = (VP x MW) / S.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
97.54
at the temperature of:
20 °C
