Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
