Additional information

Various predicted data for the target 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) were reviewed for the bioaccumulation end point which are summarized as below:

In a prediction done using BCFBAF Program (v3.00) model of Estimation Program Interface (EPI suite 2017) the estimated bio concentration factor (BCF) for 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) is 3.162 L/kg wet-wt at 25 deg. c which does not exceed the bioconcentration threshold of 2000.

In another prediction done using Bio-concentration Factor (v12.1.0.50374) of (ACD (Advanced Chemistry Development)/I-Lab predictive module, 2017) module Bio-concentration Factor at range pH 1-14  of 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 (CAS no. 93941-80-1) estimated to be 1.0 dimensionless.

Next predicted data was estimated using Sci Finder database (American Chemical Society (ACS), 2017) Bioconcentration factor (BCF) 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 at pH 1-10 and temperature 25 °C was estimated to be 1.0 dimensionless.

Using Chemspider-ACD/Phychem suite prediction model of Royal Society of Chemistry (2017).The Bioconcentration factor (BCF) 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 at pH 5.5 and pH 7.4 was estimated to be 1.0 dimensionless.

On the basis of above results for 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 EPI suite, ACD labs, Sci Finder database and Chem-Spider, 2017) it can be concluded that the BCF value of test substance ranges from 1.0 to 3.162 L/kg which does not exceed the bioconcentration threshold of 2000, indicating 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 is not expected to bioaccumulate in the food chain.
