Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
log Koc > 5.63 at 35 °C (OECD 121)
Key value for chemical safety assessment
Additional information
The adsorption/desorption potential of 2-hexyldecanoic acid[4-(6-tert-butyl-7-chloro-1H-pyrazolo[1,5-b][1,2,4]triazol-2-yl)phenylcarbamoyl]methylester (UM-235) to soil and sewage using HPLC was evaluated in a study by Brekelmans (2004). This test was conducted according to OECD Guideline 121 under GLP conditions. Because the substance is not ionized for more than 10% within pH 5.5 to 7.5, the mobile phase used during the HPLC method was not buffered. The resulting log Koc value was determined to be > 5.63 and the Koc > 43,000 at 35 °C.
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.
