Spectrophotometric Assay of Pyridoxine Hydrochloride (Vitamin B6) in Pharmaceutical Preparations and Serum Via Arsenazo III- Cerium (III) Reaction
A simple, rapid, accurate and precise spectrophotometric method is proposed for determination of pyridoxine hydrochloride (Vitamin B6) in pure form and in its pharmaceutical preparations and serum. The method is based on the oxidation-reduction reaction between vitamin B6 and cerium (IV) ion (ceric ion), then the subsequent reaction of cerium (III) with arsenazo III reagent in acidic medium in ...
متن کاملNormal and reverse flow injection–spectrophotometric determination of thiamine hydrochloride in pharmaceutical preparations using diazotized metoclopramide
Simple and sensitive normal and reverse flow injection methods for spectrophotometric determination of thiamine hydrochloride (THC) at the microgram level were proposed and optimized. Both methods are based on the reaction between THC and diazotized metoclopramide in alkaline medium. Beer's law was obeyed over the range of 10-300 and 2-90 μg/mL, the limits of detection were 2.118 and 0.839 μg/m...
متن کاملValidated Colorimetric Assay of Clonidine Hydrochloride from Pharmaceutical Preparations
Clonidine hydrochloride is an antihypertensive agent used for migraine prophylaxis, attention deficit hyperactivity disorder, menopausal flushing and Tourette syndrome. The quantity of the active substance in pharmaceutical preparations must be within specific limits, in agreement with the respective label claim. Therefore, the aim of this study was to establish the conditions for two spectroph...
