Description of key information
Adsorption / desorption
KOCWIN model (v2.00) of Estimation Programs Interface (EPI Suite, 2017) was used to predict the soil adsorption coefficient i.e Koc value of test chemical 2 -[(4 -amino-3 -methoxy phenyl)sulphonyl]ethyl hydrogen sulphate (CAS No. 26672 -22 -0). The soil adsorption coefficient i.e Koc value of 2-[(4-amino-3-methoxyphenyl)sulphonyl]ethyl hydrogen sulphate was estimated to be 19.88 L/kg (log Koc=1.2983) by means of MCI method (at 25 deg C). This Koc value indicates that the substance 2-[(4-amino-3-methoxyphenyl)sulphonyl]ethyl hydrogen sulphate has a negligible sorption to soil and sediment and therefore have rapid migration potential to ground water.
Additional information
Adsorption / desorption
Various predicted data for the target compound 2-[(4-amino-3-methoxyphenyl)sulphonyl]ethyl hydrogen sulphate (CAS No. 6470-17-3) were reviewed for the adsorption end point which are summarized as below:
In aprediction done using theKOCWIN Program(v2.00) of Estimation Programs Interface (EPI Suite, 2017) was used to predict the soil adsorption coefficient i.e Koc value of test chemical 2 -[(4 -amino-3 -methoxy phenyl)sulphonyl]ethyl hydrogen sulphate (CAS No. 26672 -22 -0). The soil adsorption coefficient i.e Koc value of 2-[(4-amino-3-methoxyphenyl)sulphonyl]ethyl hydrogen sulphate was estimated to be 19.88 L/kg (log Koc=1.2983) by means of MCI method (at 25 deg C).
The Soil Adsorption Coefficient i.e Koc value of test substance 2-[(4-amino-3-methoxyphenyl)sulphonyl]ethyl hydrogen sulphate (CAS no. 26672 -22 -0) was estimated using Adsorption Coefficient module (v12.1.0.50374) program as Koc 1 (log Koc = 0) at pH range 1-14 respectively(ACD (Advanced Chemistry Development)/I-Lab predictive module, 2017).
In an another prediction done by using ChemSpider Database (2017),the Soil Adsorption Coefficient i.e Koc value of test substance 2-[(4-amino-3-methoxyphenyl)sulphonyl]ethyl hydrogen sulphate (CAS no. 26672 -22 -0) was estimated. The adsorption coefficient (Koc) value of substance 2-[(4-amino-3-methoxyphenyl)sulphonyl]ethyl hydrogen sulphate was estimated to be 1 (Log Koc = 0) at pH 5.5 and 7.4, respectively.
Additional soil adsorption coefficient i.e Koc value of test chemical2-[(4-amino-3-methoxyphenyl)sulphonyl]ethyl hydrogen sulphate (CAS No. 26672 -22 -0)was estimated using the SciFinder database (American Chemical Society (ACS), 2017).The soil adsorption coefficient i.e Koc value of 2-[(4-amino-3-methoxyphenyl)sulphonyl]ethyl hydrogen sulphate was estimated to be 1 (log Koc = 0) (at 25 deg C).
On the basis of above overall results for target chemical 2-[(4-amino-3-methoxyphenyl)sulphonyl]ethyl hydrogen sulphate (from EPI suite, ACD labs,ChemSpider and SciFinder database,2017), it can be concluded that the Koc value of test substance 2 -[(4 -amino-3 -methoxyphenyl)sulphonyl]ethyl hydrogen sulphate ranges from1–19.88indicating that the test chemical 2-[(4-amino-3-methoxyphenyl)sulphonyl]ethyl hydrogen sulphate has a negligible sorption to soil and sediment and therefore have rapid migration potential to ground water.
