Use of Charge Transfer Complexation Reactions for the Spectrophotometric Determination of Sumatriptan in Pharmaceuticals

Use of charge transfer complexation reaction for the spectrophotometric determination of bupropion in pharmaceuticals and spiked human urine

This is the first report on use of two visible spectrophotometric methods for the determination of bupropion hydrochloride (BUPH) in pharmaceuticals and spiked human urine. Bupropion is a second-generation antidepressant agent which is also used in the management of smoking cessation. The methods are based on charge transfer complexation reaction of bupropion base (BUP) as n-electron donor with...

Spectrophotometric Determination of Rabeprazole Sodium Using Two Charge Transfer Complexation Reactions

Article history: Received on: 07/09/2013 Revised on: 19/09/2013 Accepted on: 23/11/2013 Available online: 29/11/2013 This work presents two simple and direct spectrophotometric methods for determination of rabeprazole sodium (RB) through charge transfer complexation reactions. The first method is based on the reaction of the drug with p-chloranilic acid (p-CA) in acetonitrile to give a red colo...

Application of Charge Transfer Complexation Reaction for the Spectroscopy Determination of Anticonvulsant Drug Primidone

The interaction of the perimidone drug in solution state with the σ-acceptor iodine, the aliphatic π-acceptor tetracyanoethylene (TCNE) and the aromatic π-acceptor 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) have been studied through the initial formation of ionic intermediate to charge transfer (CT) complex in methanol at room temperature. The spectral studies of the complexes were determi...
