    Abstract: Azo ligand 4-((2-hydroxy-3, 5-
dimethylphenyl)diazenyl) benzoic acid was derived from
4-aminobenzoic acid and 2, 4-dimethylphenol. Azo dye
was identified by (CHN) analysis and (UV-Vis, FT-IR
and <sup>1</sup>H-NMR). Attended compounds have been
identified by utilizing atomic absorption flame, FTIR
also UV-Vis spectrum manners and conductivity
ministrations.
