Description of key information

Calculation with HENRYWIN v3.20 (EPIWIN software by US-EPA), Henry´s Law Constant: 0.0000000237 Pa*m³/mol 

Key value for chemical safety assessment

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

Additional information

The prediction for the distribution between aqueous solution and air for the test substance was determined by the computer program HENRYWIN v3.20 (EPIWIN software) by US-EPA (Chemservice S.A., 2011). The program calculates the Henry´s Law Constant based on the Bond Method of 0.0000000237 Pa*m³/mol (2.37 E-008 Pa*m³/mol) at an ambient temperature of 25 °C. The Group Method shows an "Incomplete Result". No GLP criteria are applicable for the usage of this tool, but due to the fact that it is a scientifically accepted calculation method the estimations performed are reliable with restrictions and can be used for the chemical safety assessment.
