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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Koc (soil A-F adsorption, Freundlich): 40.1, 42.2, 38.5, 83.6, 39.2, 48.7 Goodyear 1998
Koc (Soil #1 -5, adsorption, mL/g) : 46.9, 13.0, 16.2, 37.1, 10.4 S.Connor 2017
Kdesoc (Soil # 1 -5, desorption, mL/g): 68.0, 13.0, 20.1, 54.7, 16.4 S.Connor 2017
Key value for chemical safety assessment
Additional information
For (2R)-2-(4-{[5-(trifluoromethyl)pyridin-2-yl]oxy}phenoxy)propanoic acid, Koc (adsorption, Freundlich) values were determined in 6 soils(Goodyear 1998) in the range of 38.5 to 83.6 mL/g (40.1, 42.2, 38.5, 83.6, 39.2 and 48.7 mL/g) and the Koc in 5 soils (S. Connor 2017) were in the range of 10.4 to 46.9 mL/g.
The difference could be justified by the different physico-chemical properties of test soils for the two studies.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
