Description of key information

Adsorption/desorption:

The Soil Adsorption Coefficient i.e. Koc value of test chemical 2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile (CAS No. 12236-25-8) was estimated using EPI suite KOCWIN Program (v2.00) as 96.75 L/kg (log Koc= 1.9858) by means of MCI method at 25 deg. C.  This log Koc value indicates that test chemical 2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile has low sorption to soil and therefore test chemical has moderate migration potential to ground water.
