The research contains two parts , The first part contained the process of synthesis a new azo derivative called 3-(4-(dimethylamino)phenyl)diazenyl)-2-hydroxy-5-sulfobenzoic acid from diazonium salt pairs of (N1,N1-dimethylbenzene-1,4-diamine dihydrochloride) with 2-hydroxy-5-sulfobenzoic acid dihydrate , The reagent Chemical Formula (C15H15N3O6S) and the molecular weight was (365.36 g/mol) , The reagent powder has greenish color , The pure reagent melting point is ( 183-185 °C) , It is soluble in alcoholic solvent like ethanol absolute , the reagent characterizes by many spectroscopic methods (UV-Visible, FT-IR, mas spectrum 13CNMR and 1HNMR).
