Description of key information

Adsorption/desorption:

The Soil Adsorption Coefficient i.e. Koc value of test chemical Trisodium 2-[(E)-2-(3-methyl-5-oxo-1-{4-[2-(sulfonatooxy)ethanesulfonyl]phenyl}-4,5-dihydro-1H-pyrazol-4-yl)diazen-1-yl]naphthalene-1,5-disulfonate  (CAS No. 20298-05-9) was estimated using EPI suite KOCWIN Program (v2.00) as 12850 L/kg (log Koc= 4.10) by means of MCI method at 25 deg. C. This log Koc value indicates that test chemical Trisodium 2-[(E)-2-(3-methyl-5-oxo-1-{4-[2-(sulfonatooxy)ethanesulfonyl]phenyl}-4,5-dihydro-1H-pyrazol-4-yl)diazen-1-yl]naphthalene-1,5-disulfonate has  strong sorption to soil and therefore have negligible  to slow migration potential to ground water.
