Simple and sensitive, direct current polarographic (DCP) and differential pulse polarographic (DPP) methods have been developed for the qualitative as well as quantitative analysis of 5-amino-1-cyclopropyl-7 (cis-3,5 dimethyl-1-piperazinyl)-6,8-difluoro-1,4-dihydro-4-oxo-3-quinoline carboxylic acid (sparfloxacin). The developed methods have been(More)
Direct current polarography and differential pulse polarographic methods have been developed for the qualitative as well as quantitative analysis of vitamin B1, B2 and B6. Thiamin (vitamin B1) produced a well-defined wave in 0.1 M KCl at pH 5.2 with E(1/2)=-1.2 V and E(p)=-1.22 V versus saturated calomal electrode (SCE). Riboflavin (vitamin B2) gave two(More)
The qualitative and quantitative analysis of an antibiotic drug, 5-amino-1 cyclopropyl-7 (cis-3, 5 dimethyl-1-piperazyl)-6,8- dihydro-1, 4 dihydro-4-oxo-3-quinoline carboxylic acid (Sparfloxacin, SFX) and its pharmaceutical formulation i.e.sparx-100 tablet, has been done using polarographic and amperometric methods. Complexation behavior of SFX with Fe(II),(More)
Physicochemical, Microbial and Pharmacological studies on Fe(III)-Dacarbazine complex have been done in solid and aqueous phase. On the basis of elemental analysis, polarographic studies, amperometric titrations and IR spectral studies the probable formula for the complex has been worked out to be 1:1, Fe(III)-Dacarbazine. The metal ligand interaction has(More)
Physicochemical, microbial and pharmacological studies on Fe (III)--Tamoxifen complex have been carried out in solid and aqueous phases. On the basis of elemental analysis, polarographic studies, amperometric titrations and IR spectral studies the probable formula for the complex has been worked out to be 1:1, Fe(III)--Tamoxifen. A tentative structure has(More)
The electrochemical behavior of quinine was investigated by cyclic voltammetry (CV) and square wave voltammetry (SWV) using surfactant. The reduction peak current of quinine increases remarkably in presence of 1% CTAB. Its electrochemical behavior is quasi-reversible in the Britton-Robinson buffers of pH 10.38 by exhibiting the well-defined single cathodic(More)
Simple, rapid and accurate voltammetric methods viz. DCP, DPP and DPASV have been presented for the trace determination of gold and other transition metals in quartzite rock sample. The analysis has been performed using 0.1 M(NH4)2 tartrate, 0.1 M NaClO4 and 1 M NaOH as supporting electrolyte with 0.001% gelatin as maximum suppressor. The results show the(More)
Present communication deals with the synthesis of complexes of [N-(p-tolylsulphonyl)-N'-n butyl-urea], with certain transition metals viz. Cu(II), Zn(II), Fe(II) and Cd(II). Structures of all the complexes have been established on the basis of their consistent elemental and spectral analysis. Also, it reports their in vivo hypoglycemic screening on albino(More)
The electroanalytical behavior of Zn(II)-baclofen complex has been described by direct current polarographic (DCP) method. The complex of transition metal Zn(II) with baclofen, [4-amino-3(4-chlorophenyl) butanoic acid, has been prepared and characterized on the basis of elemental analysis, IR-spectral, polarographic and amperometric studies. The(More)
The coordination chemistry of iron (III) is the environment of an antihistaminic drug, promethazine has been explained to include a low spin, six-coordinate complex [Fe(Prometha)2(H2O) Cl] Cl2. Metaldrug interaction in vitro in aqueous KCl phase was studied polarographically at physiological pH and temperature. On the basis of elemental, magnetic,(More)
