Determination 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...

Charge transfer complexes of paraquat with drugs

Molecular complexes of paraquat (PQ) with a few drug intermediates in alkaline medium, viz. 2,4,6-trimethylphenol, 4-benzyloxyphenol, 2-cyanophenol, 4-cyanophenol and a few drugs, viz. diclofenac sodium, salmeterol, omeprazole, esomeprazole and pantoprazole in methanol have been studied spectrophotometrically. All the complexes exhibit one charge transfer band each in the region where neither o...

Charge transfer complexes of chloranil with drugs

The study of charge transfer (CT) complexes of chloranil with drugs (Naproxen, Nerolin, Methyl anthranilate, Isoxsuprine and Nylidrin) showed that there is a significant interaction between the acceptor and donors as evidenced by colour changes and absorption spectra. From the position of CT bands, the ionization potentials (IPs) of donors were evaluated using appropriate equations. The donor’s...

electrochemical study of some charge-transfer complexes involving amitriptyline and nortriptyline and determination of drugs

spectrophotometric and electrochemical studies were successfully used in quantitative analysis of amitriptyline hydrochloride (ath) and nortriptyline hydrochloride (nth). conductometric titration were carried out in equeous solution using iodide and dopamine and serotonine as titrant. two new methods using spectrophotometry are dascribed for the determination of (ath) and (nth) with potassium b...
