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.

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.
