Spectrophotometric Determination of Isoxsuprine Hydrochloride as Base Form in Pharmaceutical Formulation through Charge Transfer Complexation


Two simple and selective spectrophotometric methods are described for the determination of isoxsuprine hydrochloride (ISX·HCl) as base form in bulk drug and in injections and tablets. The methods are based on the molecular charge-transfer complexation of ISX base (ISX) with either p-chloranilic acid (PCA) or 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ… (More)
