Description of key information
Adsorption and desorption:
The Soil Adsorption Coefficient i.e Koc value of 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (CAS No: 27059-08-1) was estimated using EPI suite KOCWIN Program (v2.00) program as Koc 15.11 L/kg (log Koc=1.179) by means of MCI method at 25 deg.C. This Koc value indicates that the substance 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate has a negligible sorption to soil and sediment and therefore have rapid migration potential to groundwater.
Additional information
Adsorption and Desorption:
Many studies have been carried out to predict to Adsorption coefficient i.e., Koc Value of target chemical 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (CAS No: 27059-08-1) the results of different prediction studies are summarized below.
The Soil Adsorption Coefficient i.e Koc value of 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (CAS No: 27059-08-1) was estimated using Estimation programe interface (EPI suite, 2017) KOCWIN Program (v2.00) as Koc 15.11 L/kg (log Koc=1.179) by means of MCI method at 25 deg.C. This Koc value indicates that the substance 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate has a negligible sorption to soil and sediment and therefore have rapid migration potential to groundwater.
Another prediction study done using (ACD (Advanced Chemistry Development)/I-Lab predictive module, 2017) by Adsorption Coefficient module (v12.1.0.50374) program.The Soil Adsorption Coefficient i.e Koc value of test substance 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate was estimated at different pH as Koc 1 dimensionless (log Koc= 0) at pH range 1-2, Koc 4.66 dimensionless( log koc=0.7) at pH 3, Koc range from 32.1 to 104 dimensionless( log koc range=1.5-2.0) at pH 4 -14. By considering log Koc values at pH 6, 7 and 8 indicate that the 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate has a low sorption to soil and sediment and therefore have moderate to low migration potential to groundwater.
Next study was done by using Sci Finder database ( American chemical society (ACS) 2017). Soil Adsorption coeeficient was estimated for the test chemical 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate ( CAS no. 27059 -17 -3) was in range 1-7.70 ( log koc range =0-0.88) at pH 1 -3 and temperature 25 oC and at pH 4-14 Koc value range from 53.0-179 ( log Koc range= 1.72-2.25) and temperature 25 °C. These Koc values at pH 6, 7 and 8 and temperature 25 °C indicate that the test chemical 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate has low sorption to soil and sediment and therefore have moderate migration potential to groundwater.
Another prediction done by using the Chemspider - ACD/PhysChem Suite 2017.Soil Adsorption/Mobility study was conducted for the test chemical 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (CAS No: 27059-08-1) to estimate its Koc value at pH 5.5 and pH 7.4. The adsorption coefficient i.e Koc value of test substance 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate at pH 5.5 was estimated to be 120.33 ( log koc=2.080) and pH 7.4 was estimated to be 129.35 (log koc=2.111).These Koc value at pH 5.5 and pH 7.4 indicates that the test chemical 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate as low sorption to soil and sediment and therefore have moderate migration potential to groundwater.
One more prediction done from CompTox Chemistry Dashboard using OPERA (OPEn (quantitative) structure-activity Relationship Application) V1.02 model in which calculation based on PaDEL descriptors (calculate molecular descriptors and fingerprints of chemical) the adsorption coefficient i.e KOC for test substance 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (CAS no.27059 -08 -1) was estimated to be 248 L/kg (log Koc = 2.394) .The predicted KOC result based on the 5 OECD principles. Thus based on the result it is concluded that the test substance 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate has a low sorption to soil and sediment and therefore have moderate migration potential to ground water.
On the basis of above studies overall results for target chemical 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (from EPI suite, ACD labs,SciFinder, ChemSpider database and CompTox Chemistry Dashboard,2017), it can be concluded that the Koc value of test substance 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate ranges from 15.11 -179 ( log Koc= 1.17 -2.252) indicating that the test chemical 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate has a low sorption to soil and sediment and therefore have moderate migration potential to groundwater.
