The Henry's Law constant for caffeic acid is estimated as 1.4X10-16 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that caffeic acid is expected to be essentially nonvolatile from water surfaces(2). Caffeic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.5X10-7 mm Hg(SRC), determined from a fragment constant method(3).

The Koc of caffeic acid is estimated as 100(SRC), using a log Kow of 1.15(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that caffeic acid is expected to have high mobility in soil. The pKa of caffeic acid is 4.62(4), indicating that this compound will primarily exist in anion form in the environment and anions generally do not adsorb to organic carbon and clay more strongly than their neutral counterparts(5).
