Additional information

(Q)SAR-modelled KOC values for isophthalic acid (obtained with the KOCWIN v2.00 model of the US EPA) range from 11.86 to 79.24 L/kg. Based on these values, isophthalic acid is classed as moderately to very mobile and is expected to have a low tendency to adsorb to soils and sediments. KOC may be influenced by and vary significantly in response to pH. Under alkaline conditions, isophthalic acid will rapidly be converted to salts whose KOC may be expected to be lower (mobility higher) than that of the free acid.
