In this work, the study of the6-chloro-4-hydroxy-3-phenyl pyridazine compound, (C10 H7 N2 O Cl with synonym 4-pyridazinol, 6-chloro-3-phenyl-), was verified experimentally by using the Fourier Transformed Infrared (FT-IR), micro-Raman and UV/vis (in N,N-dimethylformamide solvent) spectroscopies. Furthermore, the optimized molecular geometry, conformatinal analysis, vibrational frequencies, the simulated UV/vis spectra (in gas and in N,N-dimethylformamide solvent), 1H and 13C NMR chemical shift (in gas, in chloroform and N,N-dimethylformamide in solvents) values, HOMO-LUMO analysis, the molecular electrostatic potential (MEP) surface and thermodynamic parameters ofthe6-chloro-4-hydroxy-3-phenyl pyridazine compound were calculated by using DFT/B3LYP method with 6–311++G(d,p) basis set in ground state. The comparison of the calculated and vibrational frequencies with the experimental values provides important information about the title compound.
