Abstract

AbstractIn the present study, the spectroscopic investigation of pyriproxyfen (PYR) has been carried out using density functional theory and experimental methods. The FT‐IR, 1H and 13C NMR spectra of PYR were recorded, interpreted and compared with the theoretical spectra. The polarizability and hyperpolarizabilities are responsible for higher lipophilicity which leads to the acute aquatic toxicity of the PYR molecule. The UV‐Visible spectra of PYR exhibited the presence of π π* transition between the π‐orbitals of phenoxyphenyl and pyridyl ring. The standard entropy, heat capacity at constant volume and total energy have been computed to assess the toxicity of the compound. Molecular docking revealed the insecticidal potential of PYR owing to the presence of hydrogen bond interactions between PYR and mosquito juvenile hormone binding protein of aedes aegypti. The biophysical study predicts the possible DNA‐PYR interactions and carcinogenic properties of PYR molecule.
