Additional information


Soil Adsorption coefficient (Koc) value of 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid is estimated to be 10 by MCI method(EPI Suite) and Sabljiic molecular connectivity method(DEPA QSAR study) indicating it has high mobility in the soil.Thus the substance shows negligible sorption to soil and sediment and rapid migration potential to groundwater.The key value of 10(25 deg c) when converted at 20 deg c is equivalent to 8.

Henrys law constant:

Henry's Law states that at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. Henry's law constant value of 3-acetamido-5-amino-4- hydroxy benzene sulphonic acid is estimated to be 1.06E-22 atm-m3/Mole=1.074045106e-17 Pa m³/mol by bond contribution method.
