Impurity profiling of mycophenolate mofetil with the assisstance of desirability function in method development
(Taylor & Francis Inc, Philadelphia, 2011)
Multicriteria decision making methodology in combination with experimental design has been applied for optimization of stability-indicating LC/DAD method of Mycophenolate mofetil and its degradation products. Via fractional ...
HPLC evaluation of solvolysis of a novel ester fluocinolone acetonide 21-(2'-phenoxypropionate) in comparison with fluocinonide
(Taylor & Francis Inc, Philadelphia, 2011)
In this study the solvolysis of novel fluocinolone acetonide 21-(2'-phenoxypropionate) in comparison with fluocinonide was analyzed in order to evaluate this process as an in vitro model for prodrug activation. The solvolysis ...
An Experimental Design Approach to Selecting the Optimum HPLC Conditions for the Determination of 2-Arylimidazoline Derivatives
(Taylor & Francis Inc, Philadelphia, 2009)
In order to improve the chromatographic resolution (Rs) with a good analysis time, experimental designs were applied for multivariate optimization of the experimental conditions of an isocratic reversed phase high performance ...
Estimation of lipophilicity and retention behavior of some alpha adrenergic and imidazoline receptor ligands using rp-tlc
(Taylor & Francis Inc, Philadelphia, 2014)
The chromatographic behavior of 16 alpha adrenergic and imidazoline receptor ligands has been studied by reversed-phase thin-layer chromatography (RP-TLC) on RP-18 and CN stationary phases. Retention constant R-M(0) was ...
Forced degradation study of torasemide: Characterization of its degradation products
(Taylor & Francis Inc, Philadelphia, 2013)
Torasemide was subjected to forced degradation studies. Stress conditions were varied concerning hydrolysis (acid, base, and neutral), oxidation, photolysis, and thermal degradation in order to identify the potential ...
Influence of selected mobile phase properties on the TLC retention behavior of ziprasidone and its impurities
(Taylor & Francis Inc, Philadelphia, 2017)
Influence of nine different solvents, either alone or in a mixture, on the retention behavior of ziprasidone and its five impurities were examined by normal-phase thin-layer chromatography. Migration distances of the ...
Investigation of the retention mechanisms of amlodipine besylate, bisoprolol fumarate, and their impurities on three different HILIC columns
(Taylor & Francis Inc, Philadelphia, 2018)
Using theoretical models, retention mechanisms of amlodipine besilate and its impurities D, E, and F were tested, as well as bisoprolol fumarate and its impurities A, C, K, and L. Appropriate theoretical retention models ...
TLC determination of tiapride hydrochloride and its impurities in pharmaceuticals
(Taylor & Francis Inc, Philadelphia, 2012)
A simple and sensitive HPTLC method for separation and determination of tiapride hydrochloride and its degradation products has been developed and evaluated. Analysis of tiapride hydrochloride and impurities III, VII, and ...
Investigation of tropicamide and benzalkonium chloride stability using liquid chromatography
(Taylor & Francis Inc, Philadelphia, 2012)
In this study, a development of stability indicating method (SIM) that could be used to detect a decrease in the amount of tropicamide and benzalkonium chloride due to their degradation is described. In the method development, ...
TLC determination of glimepiride and its main impurities in pharmaceuticals
(Taylor & Francis Inc, Philadelphia, 2013)
A quantitative TLC method was developed for the simultaneous separation and quantification of glimepiride and its main degradation impurities, glimepiride-sulfonamide, and glimepiride-carbamate. Chromatographic analysis ...
