A new sensitive and seleactive method for rapid and accurated determination of nitrofarazone is described. The nitrofurazone is reacted with hydroxyl-amine hydrochloride in alkaline medium to give hydroxamic acid which forms the purple violet coloured complex with iron (III), FeCl3, in acidic medium. The nitrofurazone was determined in presence of commonly used drugs and additives. The results obtained by the proposed and B.P. methods were compared.
