Preparation and properties of Cu(II) complexes with N,N’,N',N’’’-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc) and pseudohalides(NCO- orNCSe-): Part II / Dobijanje i osobine CU(II)kompleksa Sa N,N’,N',N’’’-tetrakis(2-piridilmetil)-1,4,8,11-tetra a za ciklotetradekanom(tpmc)i pseudo halogenidima (NCO- ili NCSe-) - II deo
(Srpsko hemijsko društvo, Beograd, 2004)
Two new Cu(II) complexes with N,N’,N",N’’’-tetrakis(2-pyridylmethyl) -1,4,8,11-tetraazacyclotetradecane (tpmc) and pseudohalides (NCO- or NCSe-) were isolated. Elemental analyses (C, H, N, Cu) corresponded to the formulas ...
Electroreduction of cefetamet on mercury, platinum and gold electrodes / Elektroredukcija cefetameta na elektrodama od žive, platine i zlata
(Srpsko hemijsko društvo, Beograd, 2000)
The electroreduction of cefetamet (CEF) using gold and platinum electrodes has been investigated in slightly alkaline medium (pH 8.40) where adsorption, previously observed at mercury electrode, was pronounced. This ...
Spectrophotometric determination of thioctic (α-lipoic) acid in water and pharmaceutical preparations / Spektrofotometrijsko određivanje tioktinske kiseline u vodi i farmaceutskim preparatima
(Srpsko hemijsko društvo, Beograd, 2007)
A spectrophotometric method is described for the assay of thioctic acid. The method is based on the reaction between the drug and palladium(II) chloride. In this reaction, a yellow-colored, water soluble product with a 1:1 ...
Monitoring of the photochemical stability of carvedilol and its degradation products by the RP-HPLC method / Praćenje fotohemijske stabilnosti karvedilola i njegovih degradacionih proizvoda RP-HPLC metodom
(Srpsko hemijsko društvo, Beograd, 2007)
A sensitive, selective, precise and stability-indicating, new high-performance liquid chromatographic method for the analysis of carvedilol both as a bulk drug and in formulations was developed and validated. As the method ...
Normal-phase thin-layer chromatography of some angiotensin converting enzyme (ACE) inhibitors and their metabolites / Normalno-fazna tankoslojna hromatografija nekih ACE inhibitora i njihovih metabolita
(Srpsko hemijsko društvo, Beograd, 2009)
The separation and chromatographic behaviour of five ACE (angiotensin converting enzyme) inhibitors and their four active metabolites were investigated by normal-phase thin-layer chromatography on silica using several mono- ...
