Description of key information

Henry’s Law constant (H) calculated according to EU Directive 91/414/EEC: 2.15E-06 Pa m³/mol (20 °C).

Key value for chemical safety assessment

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

Additional information

The Henry's Law constant of the substance was calculated from the vapour pressure, water solubility and molecular weight values (Bascou, 2002). If the substance is exposed to water, it will not evaporate into the atmosphere from the water surface because of its low Henry's Law constant of 2.15E-06 Pa m³/mol (20 °C).
