Description of key information

The calculated Henry's Law Constant of 2,6-dibromo-4-cyanophenyl octanoate ranged from 2.1E-3 at 20 °C to 1.9E-1 Pa m³/mol at 40 °C.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0.19
at the temperature of:
20 °C

Additional information

The endpoint “Henry’s Law constant” is not a data requirement for the registered substance. However, for the sake of completeness this endpoint is covered by a short summary of the available data.

 

In the available GLP study, the Henry's Law Constant was calculated from the vapor pressure of the compound at 20 °C and the water solubility at 20 °C. The Henry's Law Constant was calculated as 1.9E-1 Pa m³/mol.

 

In a second GLP study, the Henry's Law Constant was calculated from the vapor pressure of the compound at 40 °C and the water solubility at 20 °C. A Henry's Law Constant of 2.1E-3 Pa m³/mol was calculated.
