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 کاملSpectroscopic analytical study for the charge-transfer complexation of certain cephalosporins with chloranilic acid.
Studies were carried out to develop a simple, rapid and accurate spectrophotometric method for the analysis of fifteen cephalosporins. The method depends on the charge-transfer complexation reaction between any of these drugs as an n-electron donor and p-chloranilic acid (p-CA) as a pi-acceptor to form a violet chromogen measured at 520 nm. Different variables affecting the reaction were studie...

15 صفحه اولSpectrophotometric 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...
متن کامل2,4-Diamino-6-methyl-1,3,5-triazine methanol solvate
The crystal structure of the title compound, C(4)H(7)N(5)·CH(4)O, is determined by an extensive network of hydrogen bonding. A sequence of centrosymmetric dimeric associations, formed by two different N-H(amino)⋯N(ring) hydrogen bonds, connects the triazine rings into a planar mol-ecular tape. The methanol solvent mol-ecules act as di-acceptors and mono-donors of hydrogen bonds and inter-link, ...
