Environmental Fate and Exposure Potential
Environmental Fate/Exposure Summary:
The rate constant for the vapor-phase reaction of shikimic acid with photochemically-produced hydroxyl radicals has been estimated as 6.1X10-11 cu cm/molecule-sec at 25 deg C(SRC) using a structure estimation method(1,SRC). This corresponds to an atmospheric half-life of about 6.3 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1,SRC). Shikimic acid is not expected to undergo hydrolysis(SRC) or direct photolysis in the environment due to the lack of functional groups to hydrolyze(3) or absorb in the environmental spectrum, respectively.
