Journal ArticleDOI
Smart stability-indicating spectrophotometric methods for determination of binary mixtures without prior separation.
TL;DR: The proposed ratio subtraction method was validated and found to be suitable as a stability-indicating assay method for vincamine in pharmaceutical formulations and it was valid in the presence of up to 80% degradation product.
Journal ArticleDOI
Stability-indicating electrochemical methods for the determination of meclophenoxate hydrochloride and pyritinol dihydrochloride using ion-selective membrane electrodes.
TL;DR: The construction and electrochemical response characteristics of polyvinyl chloride (PVC) membrane sensors for the determination of meclophenoxate hydrochloride and pyritinol dihydrochloride in presence of their degradation products are described.
Journal ArticleDOI
Kinetic Study on the Degradation of Meclophenoxate Hydrochloride in Alkaline Aqueous Solutions by High Performance Liquid Chromatography
TL;DR: A high performance liquid chromatographic method was developed and validated for determination of meclophenoxate hydrochloride (I) in the presence of its degradation product (p-chlorophenoxy acetic acid) (II) and successfully applied to the analysis of a pharmaceutical formulation containing (I).
Journal ArticleDOI
Stability-indicating methods for determination of pyritinol dihydrochloride in the presence of its precursor and degradation product by derivative spectrophotometry.
TL;DR: The proposed methods were validated and found to be suitable as stability-indicating assay methods for pyritinol in pharmaceutical formulations.
