Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
Adsorption / desorption:
The Soil Adsorption Coefficient i.e Koc value of 1-bromo-3-methoxybenzene was estimated using EPI suite KOCWIN (v2.00) program as Koc 149.9 L/kg(log Koc=2.17) by means of MCI method at 25 deg.C. This Koc value indicates that the substance 1-bromo-3-methoxybenzene has a Low sorption to soil and sediment and therefore have moderate migration potential to groundwater.
Additional information
Adsorption / desorption:
Three predicted reports from validate models for adsorption in soil/sediment endpoint of test chemical 1-bromo-3-methoxybenzene (Cas no. 2398-37-0) were reviewed as follows:
The Soil Adsorption Coefficient i.e Koc value of 1-bromo-3-methoxybenzene was estimated using EPI suite KOCWIN (v2.00) program as Koc 149.9 L/kg(log Koc=2.17) by means of MCI method at 25 deg.C. This Koc value indicates that the substance 1-bromo-3-methoxybenzene has a Low sorption to soil and sediment and therefore have moderate migration potential to groundwater.
Data from Chemspider - ACD/PhysChem Suite prediction database suggest the soil adsorption coefficient i.e Koc value of test substance 1-bromo-3-methoxybenzene to be 1089.11(log koc-3.03) at pH 5.5 and pH 7.4 and temp.25 deg.C. Koc values at different pH indicates that the substance 1-bromo-3-methoxybenzene has Moderate sorption to soil and sediment and therefore have slow migration potential to groundwater.
Whereas SciFinder, American Chemical Society (ACS); 2017 prediction database indicated the soil adsorption coefficient i.e Koc value of test substance 1-bromo-3-methoxybenzene was estimated to be 1080.0 (Log koc-3.03) at pH 1-10 and temperature 25 deg.C.
All three studies based on the prediction reports indicate the adsorption coefficient (KOC) value is in the range of 149.9 to 1089.11 (i.e log Koc range 2.17 to 3.03) at temperature 25 deg.C Thus all above results from validated predicted models indicate that the test substance 1-bromo-3-methoxybenzene (Cas no. 2398-37-0) has low to moderate mobility in soil/sediment.
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).
