Experimental and theoretical studies of carbazole-based Schiff base as a fluorescent Fe3+ probe
(Scientific Technical Research Council Turkey-Tubitak, 2018)
Synthesis of a new (E)-N1-((9-ethyl-9H-carbazol-3-yl)methylene)-5-nitrobenzene-1,2-diamine as a fluorescent chemosensor for selective detection of Fe3+ ion over a number of other metal ions is described. The method for the ...
A novel synthesis of 4-toluene 9H-carbazole-9-carbodithioate, electropolymerization and impedance study
(Budapest Univ Technol & Econ, 2014)
A novel synthesis of 4-toluene 9H-carbazole-9-carbodithioate (TCzC) was chemically synthesized and characterized by Fourier Transform Infrared (FTIR), proton nuclear magnetic resonance (H-1-NMR), and carbon nuclear magnetic ...
Development and validation of first and zero order derivative spectrophotometric methods for the determination of rilmenidine in pharmaceutical preparations and forced degradation study
(Marmara Univ, 2019)
Zero and first order derivative spectrophotometric methods were developed for the analysis of rilmenidine in pharmaceutical preparations. Absorbances of rilmenidine were measured at 224 rim for the zero order by measuring ...
