Description of key information

The Henry's Law constant for the test item was estimated to be 1.28E-01 Pa m³/mol (Bond Contribution Method) and 1.49E-04 Pa m³/mol (Group Contribution Method) at 25 °C. 

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0.128
at the temperature of:
25 °C

Additional information

The Henry’s Law constant was estimated using the QSAR model HENRYWIN v 3.20 available in EPI Suite using experimental data for water solubility and vapour pressure.

The Henry's Law constant for the test item was estimated to be 1.28E-01 Pa m³/mol (Bond Contribution Method) and 1.49E-04 Pa m³/mol (Group Contribution Method) at 25 °C. The model is considered reliable and appropriate to estimate this endpoint.
