The Henry's Law constant for pyrogallic acid is estimated as 1.57X10-10 atm-cu m/mole(SRC) derived from its vapor pressure, 4.79X10-4 mm Hg(1), and water solubility, 5.07X10+5 mg/L(2). This Henry's Law constant indicates that the neutral species of pyrogallic acid is expected to be essentially nonvolatile from water surfaces(3). The pKa of pyrogallic acid is 9.01(4), indicating that this compound will partially exist in the anion form in the environment, and anions do not volatilize(SRC). Pyrogallic acid is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of pyrogallic acid can be estimated to be 320(SRC). According to a classification scheme(2), this estimated Koc value suggests that pyrogallic acid is expected to have moderate mobility in soil. The pKa of pyrogallic acid is 9.01(3), indicating that this compound will partially exist in the anion form in the environment and anions do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
