Extractive spectrophotometric methods for determination of terbinafine hydrochloride in pharmaceutical formulations using some acidic triphenylmethane dyes
Three simple and sensitive extractive spectrophotometric methods have been described for the assay of terbinafine hydrochloride either in pure form or in pharmaceutical formulations. The developed methods involve formation of coloured chloroform extractable ion-pair complexes of the drug with bromothymol blue (BTB), bromophenol blue (BPB) and bromocresol green (BCG) in acidic medium. The extrac...
متن کاملExtractive spectrophotometric determination of levetiracetam in pharmaceutical formulations
Three simple, economical, precise, reliable and reproducible visible spectrophotometric methods (A, B and C) have been developed for the estimation of Levetiracetam in bulk as well as in Tablet formulation. The developed methods A, B and C are based on the formation of chloroform extractable complex of Levetiracetam with Bromocresol green (method A), Bromophenol blue (method B) and Bromothymol ...
متن کاملExtractive Spectrophotometric Determination of Amitriptyline Hydrochloride in Pure and Pharmaceutical Formulations
A sensitive, reproducible and accurate spectrophotometric method has been developed for determining amitriptyline hydrochloride (ATH) from its pharmaceutical formulation based on solvent extraction into chloroform of the product formed with 1, 2-naphthoquinon-4-sulphonate. The reaction and extraction was complete and quantitative at pH 1.3. The Beer’s law of yellow colored species is obeyed in ...
متن کاملDevelopment of new spectrophotometric methods for the determination of Alfuzosin hydrochloride in bulk and pharmaceutical formulations
Two simple and sensitive methods A and B for the spectrophotometric determination of Alfuzosin hydrochloride have been described. These methods are based on the formation of purple color and redviolet colored chromogens obtained when the drug was diazotized with nitrous acid followed by coupling with Phloroglucinol and Resorcinol, exhibiting λmax at 520 and 600 nm respectively. These methods ob...
متن کاملNew Spectrophotometric Methods for the Determination of Naratriptan Hydrochloride in Bulk and its Pharmaceutical Formulations
Three simple sensitive and reproducible visible spectrophotometric methods (A, B, and C) for the determination of Naratriptan hydrochloride (NTP) in bulk samples and pharmaceutical formulations are described. Method A is based on the formation of colored co-ordination complex with cobalt thiocyanate (CTC). Method B is based on the formation of colored species with citric acid acetic anhydride (...
