Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Adsorption/desorption:
The Soil Adsorption Coefficient i.e. Koc value of test chemical was estimated using EPI suite KOCWIN Program (v2.00) as 1217 L/kg (log Koc= 3.0852) by means of MCI method at 25 deg. C. This log Koc value indicates that test chemical has moderate sorption to soil and therefore test chemical has slow migration potential to ground water
Additional information
Adsorption/desorption:
Predictions and experimental studies have been reviewed from different sources of test chemical and its structurally similar read across chemical for adsorption coefficient endpoint.
In first study the Soil Adsorption Coefficient i.e. Koc value of test chemical was estimated using EPI suite KOCWIN Program (v2.00) as 1217 L/kg (log Koc= 3.0852) by means of MCI method at 25 deg. C.
In next study the koc value of test chemical was determined to be 1100 dimensionless (log Koc= 3.041) by using a structure estimation method based on molecular connectivity indices.
Last study was also experimental study reviewed from authoritative database (HSDB) the koc value of test chemical was determined to be 470 dimensionless (log Koc= 2.672) by using a structure estimation method based on molecular connectivity indices
By considering the Log Koc value all the studies mentioned above it is concluded that Log Koc value of test chemical is in range of 2.672 – 3.0852 this range log Koc value indicates that the test substance has a strong sorption to soil and therefore has negligible to slow migration potential to groundwater.
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.
