Adsorption
The Soil Adsorption Coefficient (Koc) of disodium 2-[[5-carbamoyl-1-ethyl-1,6-dihydro-2-hydroxy-4-methyl-6-oxo-3-pyridyl] azo]-4-[[4-chloro-6-[[3-[[2-( sulphonatooxy )ethyl]sulphonyl]phenyl]amino]-1,3,5-triazin-2-yl]amino]benzenesulphonate was estimated using the EPI suite KOCWIN Program (v2.00). The Soil Adsorption Coe fficient (Koc) of disodium 2-[[5-carbamoyl-1-ethyl-1,6-dihydro-2-hydroxy-4-methyl-6-oxo-3-pyridyl] azo]-4-[[4-chloro-6-[[3-[[2-(sulphonato oxy)ethyl]sulphonyl] phenyl] amino]-1,3,5-triazin-2-yl]amino]benzenesulphonate was estimated as 179 L/kg (log Koc = 2.253) by means of MCI method. The results indicate that the chem ical disodium 2-[[5-carbamoyl-1-ethyl-1,6-dihydro-2-hydroxy-4-methyl-6-oxo-3-pyridyl] azo]-4-[[4-chloro-6-[[3-[[2-(sulphonatooxy)ethyl]sulphonyl]phenyl] am ino] -1,3, 5-tri azin-2-yl]amino]benzenesulphonate (CAS No.84000-63-5) is likely to to show low tendency of sorption to soil and sediment and show moderate migration potential to groundwater.

Adsorption
In a different studies, disodium 2-[[5-carbamoyl-1-ethyl-1,6-dihydro-2-hydroxy-4-methyl-6-oxo-3-pyridyl] azo]-4-[[4-chloro-6-[[3-[[2-(sulphonatooxy)ethyl] sulph onyl] phenyl]amino]-1,3,5-triazin-2-yl]amino]benzene sulphonate(CAS No.84000-63-4) has been investigated for its soil adsorption potential to a greater or lesser extent. These include predicted and experimental study for target substance disodium 2-[[5-carbamoyl-1-ethyl-1,6-dihydro-2- hydroxy-4- methyl- 6-oxo- 3-pyridyl] azo]-4- [[4-chloro-6-[[3-[[2-(sulphonatooxy)ethyl] sulphonyl]phenyl]amino]-1,3,5-triazin-2-yl]amino]benzenesulphonate (CAS No.84000- 63-5) and for its closest read across substance disodium 6-hydroxy-5-[(2-methoxy-4-sulphonato-m-tolyl)azo]naphthalene-2-sulphonate (CAS No.- 25956 -17 -6) by consid ering its structure-activity relationships, were reviewed and are summarized as follows:
The Soil Adsorption Coefficient (Koc) of disodium 2-[[5-carbamoyl-1-ethyl-1,6-dihydro-2-hydroxy-4-methyl-6-oxo-3-pyridyl] azo]-4-[[4-chloro-6-[[3-[[2-( sulphonatooxy )ethyl]sulphonyl]phenyl]amino]-1,3,5-triazin-2-yl]amino]benzenesulphonate was estimated using the EPI suite KOCWIN Program (v2.00). The Soil Adsorption Coe fficient (Koc) of disodium 2-[[5-carbamoyl-1-ethyl-1,6-dihydro-2-hydroxy-4-methyl-6-oxo-3-pyridyl] azo]-4-[[4-chloro-6-[[3-[[2-(sulphonato oxy)ethyl]sulphonyl] phenyl] amino]-1,3,5-triazin-2-yl]amino]benzenesulphonate was estimated as 179 L/kg (log Koc = 2.253) by means of MCI method. The results indicate that the chemical disodium 2-[[5-carbamoyl-1-ethyl-1,6-dihydro-2-hydroxy-4-methyl-6-oxo-3-pyridyl] azo]-4-[[4-chloro-6-[[3-[[2-(sulphona tooxy)ethyl]sulphonyl]phenyl] am ino] -1,3, 5-tri azin-2-yl]amino]benzenesulphonate (CAS No.84000-63-5) is likely to to show low tendency of sorption to soil and sediment and show moderate migration potential to groundwater.
Moreover, based on the study from an authoritative database (Hazardous Substances Data Bank (HSDB, 2017) for a read across substance disodium 6-hydroxy-5- [(2-methoxy-4-sulphonato-m-tolyl)azo]naphthalene-2-sulphonate (CAS No.- 25956 -17 -6),the soil adsorption/mobility of disodium 6-hydroxy- 5-[(2-methoxy-4-sulphonato-m-tolyl)azo]naphthalene-2-sulphonate (CAS No.-25956-17-6) was determined. Disodium 6-hydroxy-5-[(2-methoxy-4-sulphonato- m-tolyl)azo]naphthalene-2-sulphonate (Allura Red AC dye) is expected to be mobile in soil; this compound will almost entirely exist in anion form in the enviro nment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts.
Based on the above studies for target substance and to its read across substance, it can be concluded that the chemical disodium 2-[[5-carbamoyl-1-ethyl- 1,6-dihydro-2-hydroxy-4-methyl-6-oxo-3-pyridyl] azo]-4-[[4-chloro-6-[[3-[[2-(sulphonatooxy)ethyl]sulphonyl]phenyl] am ino] -1,3, 5-tri azin-2-yl]amino]benzene sulphonate (CAS No.84000-63-5) is likely to to show low tendency of sorption to soil and sediment and show moderate migration potential to groundwater.
