Soil Adsorption / Mobility

Using a structure estimation method based on molecular connectivity indices(1), the Koc of sufentanil can be estimated to be 16,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that sufentanil is expected to be immobile in soil. The pKa of sufentanil is 8.01(3), indicating that this compound will exist partially in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
