New Spectrophotometric Determination of Hydralazine Hydrochloride in Pure form and Pharmaceutical Formulation using Potassium Ferrocyanide

Simple and selective method for the determination of hydralazine Hydrochloride in pharmaceutical formulation is described. The procedure is based on the formation of colored complex with potassium ferrocyanid. Different variables affecting the complex formation were studied and optimized. The method was used to determine 1.90-68μgmL^-1 of hydralazine Hydrochloride in the Final measured solution. The simplicity of the method permits rapid analysis and thus suitable for routine control.
