Description of key information

Adsorption/desorption:

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.

Results of predicted data of target 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 (CAS no. 93941-80-1) from three different sources by using different databases namely Bio-concentration Factor (v12.1.0.50374) module of (ACD (Advanced Chemistry Development)/I-Lab predictive module, 2017) module, another one was SciFinder Database of American Chemical society and last one was Chemspider- ACD/PhysChem Suite of Royal Society of Chemistry, 2017 were obtained at different pH ranges ACD lab pH range from 1-14, Scifinder Database at pH range 1-10 and Chemspider at pH 5.5 and 7.4. 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.
