Description of key information
Adsorption / desorption:
The Soil Adsorption Coefficient i.e Koc value of N-(2-Phenoxyphenyl)methanesulphonamide was estimated using EPI suite KOCWIN (v2.00) as Koc 358.5 L/kg (log Koc = 2.554) by means of MCI method at 25 deg.C. This Koc value indicates that the substance N-(2-Phenoxyphenyl)methanesulphonamide has a Moderate sorption to soil and sediment and therefore have slow migration potential to groundwater.
Additional information
Adsorption / desorption:
Three different predicted data from validated model for adsorption (KOC) endpoint of test substance N-(2-Phenoxyphenyl)methanesulphonamide (CAS no. 51765-51-6) were summarized as follows:
First estimation using KOCWIN model (v2.00) of EPI suite indicated the Soil Adsorption Coefficient i.e Koc value of N-(2-Phenoxyphenyl)methanesulphonamide as Koc 358.5 L/kg (log Koc = 2.554) by means of MCI method at 25 deg.C. This Koc value indicates that the substance N-(2-Phenoxyphenyl)methanesulphonamide has a moderate sorption to soil and sediment and therefore have slow migration potential to groundwater.
Another prediction model for target i.e Chemspider - ACD/PhysChem Suite suggest the soil adsorption coefficient i.e Koc value of test substance N-(2-phenoxyphenyl)methanesulfonamide was estimated to be 489.45 (log koc: 2.68 ) at pH 5.5 and 448.98 (log koc: 2.65 ) at pH 7.4 at temp.25 deg.C
Above both results are supported by another prediction database Scifinder, which indicated the soil adsorption coefficient i.e Koc value of test substance N-(2-phenoxyphenyl)methanesulfonamide was estimated to be 391 (Log koc: 2.59) at pH 1-6; 377 (Log koc: 2.57) at pH 7; 287 (Log koc: 2.45) at pH 8 at temperature 25 deg.C. This Koc value at all range of pH condition indicates that the substance N-(2-phenoxyphenyl)methanesulfonamide has moderate sorption to soil and sediment and therefore have slow migration potential to groundwater.
Thus all above available values for adsorption (log KOC) is in the range of 2.45 to 2.68 (L/kg or dimensionless) which indicates that the target substance N-(2-Phenoxyphenyl)methanesulphonamide (CAS no. 51765-51-6) is expected to have moderate mobility in soil and sediment compartment.
Henry's Law constant:
Henry's Law constant of test substance N-(2-Phenoxyphenyl)methanesulphonamide was estimated to be 0.00258 (2.58E-003)Pa-m3/mole at 25 deg.C
