Description of key information

Adsorption / desorption:

The Soil Adsorption Coefficient i.e Koc value of trisodium 2,5-dichloro-4-(4-{[5-({4-chloro-6-[(4-sulfonatophenyl)amino]-1,3,5-triazin-2-yl}amino)-2-sulfonatophenyl]diazenyl}-3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate was estimated using EPI suite  KOCWIN Program (v2.00) as Koc 872700000 L/kg (log Koc = 8.940)  by means of MCI method at 25 deg.C.

Additional information

Adsorption / desorption:

The Soil Adsorption Coefficient i.e Koc value of trisodium 2,5-dichloro-4-(4-{[5-({4-chloro-6-[(4-sulfonatophenyl)amino]-1,3,5-triazin-2-yl}amino)-2-sulfonatophenyl]diazenyl}-3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate was estimated using EPI suite  KOCWIN Program (v2.00) as Koc 872700000 L/kg (log Koc = 8.940)  by means of MCI method at 25 deg.C. This Koc value indicates that the substance trisodium 2,5-dichloro-4-(4-{[5-({4-chloro-6-[(4-sulfonatophenyl)amino]-1,3,5-triazin-2-yl}amino)-2-sulfonatophenyl]diazenyl}-3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate has very strong to soil and sediment and therefore have negligible migration potential to groundwater.
