Normal 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 کاملDevelopment and Validation of UV-Spectrophotometric Methods for Simultaneous Estimation of Cetirizine hydrochloride and Phenylephrine hydrochloride in Tablets
Without resolving mixtures of Cetirizine hydrochloride and Phenylephrine hydrochloride, simultaneous estimation has been successfully achieved by spectrophotometry. First method, simultaneous equation method employs formation and solving of mathematical simultaneous equation using 237.5 nm and 232.0 nm as the λmax of Phenylephrine hydrochloride and Cetirizine hydrochloride respectively in disti...
متن کاملSpectrophotometric Estimation of Ropinirole Hydrochloride in Tablets
A simple, sensitive, rapid, accurate and precise spectrophotometric method has been developed for estimation of ropinirole hydrochloride in bulk and tablet dosage forms. Ropinirole hydrochloride shows maximum absorbance at 250 nm with molar absorptivity of 8.703x10(3) l/mol.cm. Beer's law was obeyed in the concentration range of 5-35 mug/ml. Results of analysis were validated statistically and ...
متن کاملSpectrophotometric Assay of Phenylephrine Hydrochloride Using 4-Aminoantipyrine and Copper (II)
A new spectrophotometric method is proposed for the determination of phenylephrine hydrochloride. The method is based on the coupling of 4-aminoantipyrine (4-AAP) with Phenylephrine Hydrochloride (PEH) to give a new ligand that reacts with copper (II) in the presence of sodium tetraborate buffer solution of pH9 at 50°C with an intensely red colored chelate having maximum absorption at 480 nm. T...
متن کاملSimultaneous Spectrophotometric Estimation of Imipramine Hydrochloride and Chlordiazepoxide in Tablets
A binary mixture of imipramine HCl and chlordiazepoxide was determined by three different spectrophotometric methods. The first method involved determination of imipramine HCl and chlordiazepoxide using the simultaneous equations and the second method involved absorbance ratio method. Imipramine has absorbance maxima at 251 nm, chlordiazepoxide has absorbance maxima at 264.5 nm and isoabsorptiv...
