Spectrophotometric Determination of Oxybutynin Hydrochloride via Charge- Transfer Complexation Reaction


Two simple, accurate and reproducible spectrophotometric methods were developed for the quantitative estimation of oxybutynin hydrochloride in pure form and in pharmaceutical preparation. The methods were based on the charge transfer complex formation of oxybutynin as n-electron donor with two π-electron acceptors: 2,3-dichloro-5,6-dicayno-p-benzoquinone… (More)
