CAS RN: 51-28-5


A pKa of 4.09(1) indicates 2,4-dinitrophenol will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(SRC). 2,4-Dinitrophenol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 3.9X10-4 mm Hg(2).
