By FT-IR, FT-Raman and DFT computations spectral characterization of 3-[(4-Carboxyphenyl) carbamoyl]-4-hydroxy-2-oxo-1, 2-dihydroxy quinoline-6-carboxylic acid was performed. Computational calculations were done using B3LYP/6-31G(d’) basis set. Vibrational assignments of wavenumbers were performed on the basis of potential energy distribution. Donor acceptor interactions were evaluated using NBO analysis. To foresee the important reactive sites of the title compound we combined DFT calculations and molecular dynamics (MD) and visualized the ALIE and Fukui functions. Sensitive nature of the compound towards autoxidation and degradation in the presence of water was investigated by the calculation of BDE and RDF. By molecular docking the compound forms a stable complex with ubiquinol-cytochrome–c reductase inhibitor.
