The vibrational spectral analysis has been carried out on 4-[(E)-(4-hydroxybenzylidene)amino]-3methyl-1H-1,2,4-triazole-5(4H)-thione (HBAMTT) in order explore the chemical and pharmacological properties. The most important reactive sites have been identified employing molecular electrostatic potential map. Nonlinear optical properties are identified and the first hyperpolarizability is 80.35 times that of urea, which is standard NLO material. The molecular activity is studied from the dislocation of the frontier molecular orbitals and NBO analysis is carried to gain an insight into the charge transfer within the molecular system. Using molecular electrostatic potential map, the electrophilic and nucleophilic sites are identified. Title molecule was further investigated from the aspect of local reactivity properties by calculations of average local ionization energies (ALIE) and Fukui functions. Vulnerability towards autoxidation and hydrolysis mechanisms has been assessed thanks to the calculations of bond dissociation energies (BDE) and radial distribution functions (RDF), respectively. This information was also valuable for the initial investigation of degradation properties of the title molecule. Thanks to the molecular docking studies, it can be concluded that docked ligand forms a stable complex with AChE and could be used as a new drug for the Alzheimer's disease, myasthenia gravis and glaucoma.
