Principles of method if other than guideline:

Prediction done using ACD/Adsorption Coefficient (v12.1.0.50374).This particular module provides organic carbon adsorption coefficient (Koc) values over the entire pH scale. Calculations are performed for both neutral and ionic species present at a given pH and utilize predicted values for LogP as well as pKa.Koc values characterize the tendency for a compound to accumulate in soil.

Executive summary:

The Soil Adsorption Coefficient i.e Koc value of test substance 4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (CAS no. 93941 -80 -1) was estimated using Adsorption Coefficient module (v12.1.0.50374) program as Koc 1.0 dimensionless (log Koc= 0). This log Koc value indicates that the test substance 4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid has a negligible sorption to soil and therefore have rapid migration potential to groundwater.

The estimated Koc values from three different sources were same which is 1.0 dimensionless (Log koc = 0). This Koc value at different pH indicates that the chemical 4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid has negligible sorption to soil and sediment and therefore rapid migration potential to ground water.
