Sažetak

An accurate and sensitive photometric method for the determination of hydrnzinophthalazines is described. The method is based on the formation of the yellow azine by the action of the acid solution of p-dimethylaminobenzaldehyde. The proposed method is successfully applied on the determination of 1-hydrazinophthalazine hydrochloride (I) and 1,4-dihydrazinophthalazine sulphate (II).
