Sensitive and selective determination of riboflavin (vitamin B2) based on boron-doped diamond electrode
(Springer Wien, Wien, 2016)
In this paper, we present electrochemical behavior and determination of riboflavin in pharmaceutical tablets by square wave voltammetry using unmodified boron-doped diamond electrode. In Britton-Robinson buffer solution ...
Electrochemical determination of ajmalicine using glassy carbon electrode modified with gold nanoparticles
(Springer Wien, Wien, 2016)
A simple, sensitive, and economically viable electrochemical method for the determination of ajmalicine was developed. The procedure involves a glassy carbon electrode modified with gold nanoparticles (GCE/AuNPs). In the ...
Reactivity of (E)-4-aryl-4-oxo-2-butenoic acid arylamides toward 2-mercaptoethanol. A LFER study
(Springer Wien, Wien, 2013)
The reactivity of fifteen (E)-4-aryl-4-oxo-2-butenoic (aroylacrylic) acid arylamides toward thiols was studied, measuring the rate constants of the addition of model thiol nucleophile, 2-mercaptoethanol. The influence of ...
Reactivity of (E)-4-aryl-4-oxo-2-butenoic acid phenylamides with piperidine and benzylamine: kinetic and theoretical study
(Springer Wien, Wien, 2014)
Rates of the aza-Michael addition of piperidine and benzylamine to thirteen (E)-4-aryl-4-oxo-2-butenoic acid phenylamides (AACPs) are reported. Progress of the reaction was monitored by UV/Vis spectroscopy. The 2D NMR ...
Biological activity of two isomeric N-heteroaromatic selenosemicarbazones and their metal complexes
(Springer Wien, Wien, 2014)
New square-planar Pd(II) and Pt(II) complexes with 8-quinolinecarboxaldehyde selenosemicarbazone have been synthesized and characterized by use of elemental analysis, molar conductivity measurements, and IR and NMR ...
