The organofluorine hexahydropyrimidine derivatives are used in the drug discovery due to its steric nature to hydrogen and its extreme electronegativity. The Ethyl 5-hydroxy-2-thioxo-4-(p-tolyl)-6-(trifluoromethyl)hexahydropyrimidine-5-carboxylate (ETP5C) compound was synthesized and characterized by NMR (13C and 1H), FT-IR and UV–Vis spectroscopic techniques for experimentally and theoretically and elemental analyses, mass spectra also investigated. The most stable structure of synthesized molecule was studied by PES analysis in gas and liquid medium. The structural parameters such as bond length and bond angle of the title molecule have been obtained by DFT/B3LYP/6–311++G (d,p) set and compared with the structurally related experimental data of the compounds. The π-to-π* transition of the ETP5C molecule is identified using UV–Vis absorption spectral analysis. In addition, the chemical stability and reactivity are investigated using HOMO-LUMO analysis. The minimal HOMO-LUMO energy gap (4.6255 eV) clearly explains that the ETP5C molecule is more reactive for receptors. The nucleophilic and electrophilic regions such as active sites have been shown by MEP, ELF, LOL and Fukui functions. The second order optical effect has been explained by NLO analysis. The docking was performed with antineoplastic proteins that exhibit against the development of tumor cells.
