In this work, total and differential ionization cross sections of uracil ionized by C6+ projectiles are calculated by extending an adaptative classical trajectory Monte Carlo model recently introduced in the ion-H2O collisions context. Calculated cross sections are contrasted and benchmarked against available experimental and theoretical data at impact energies in the MeV/u range. Present results are found in good agreement with the reported experimental data at different levels of differentiability. In addition, the electron emission contributions arising from single and multiple electron ionization are explicitly determined and their partial dominance analyzed in terms of the specific angular and/or energetic ranges.
