Spectrophotometric 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 کاملSpectrophotometric determination of atropine, pilocarpine and strychnine with chloranilic acid.
In dioxan-chloroform medium the acceptor chloranilic acid forms 1:1 molecular complexes with the alkaloids atropine, pilocarpine and strychnine, with maximum absorption at 535, 527.5 and 535 nm respectively. Conformity with Beer's law allows the use of the complexes for the assay of these drugs.

متن کاملDetermination of Trimethoprim Based on Charge-Transfer Complexes Formation
A spectrophotometric study concerning the interaction between Trimethoprim (TMP) ,Sulfamethoxazole (SFMx), as n-donor and 2,3-dichloro-5,6- dicyano-P-benzoquinine (DDQ) and chloranilic acid (CA) as π-acceptor were been performed at 25°C. The results of interaction of CA and DDQwith TMP indicate the formation of a 1:1, 1:2, charge transfer complexes through non equilibrium reactions. In the case...
