Mass attenuation coefficient, effective atomic number, and electron density of 12 organic acids, acetic acid (C2H4O2), acrylic acid (C3H4O2), benzoic acid (C7H6O2), butyric acid (C4H8O2), citric acid (C6H8O7), formic acid (CH2O2), lactic acid (C3H6O3), malic acid (C4H6O5), oxalic acid (C2H2O4), salicylic acid (C7H6O3), tartaric acid (C4H6O6), and valeric acid (C5H10O2), were computed in the wide energy range of incident photon energies from 1 keV to 100 GeV. The variation of these parameters has been studied as a function of incident photon energy. Further, a comparative study of two different methods used to compute effective atomic number is completed.
