Studies on the Charge-Transfer Interaction Between Tamoxifen Citrate and Chloranilic Acid
The complex formed as a consequence of the interaction between the electron-acceptor P-chloranilic acid and an electron donor tamoxifen citrate was employed in the assay of the drug in pure powder and tablets. Chloranilic acid was found to form a charge-transfer complex in a 1:1 stoichiometric ratio, with tamoxifen citrate. The wavelength of maximum absorption for the complex was found to...

متن کاملThermodynamic and Spectrophotometric Studies of Electron Donor-Acceptor Complexation Between Loratadine and Chloranilic Acid
Purpose: To developing a simple, rapid and reliable analytical method for loratadine based on charge transfer complexation with chloranilic acid. Methods: The complex between loratadine and the complexing agent, chloranilic acid, was formed by mixing appropriate volumes of their solutions in non-aqueous media. Some features of the formed complex, such as molar ratio of the reaction and effect o...
متن کاملSpectrophotometric Determination of Astemizole and Loratadine Based on Charge-Transfer Complex Formation with Chloranilic Acid
A simple and sensitive spectrophotometric method for the assay of two antihistamines, astemizole and loratadine, is described. The determination was based on the formation of chargetransfer complexes between chloranilic acid as a p acceptor and the studied drugs as n-donors in acetonitrile solvent. The spectra, various experimental parameters, composition and formation constant of the complexes...
