2, 4-dihydroxy -5-bromo-α-phenyl acetophenone thiosemicarbazone [DHB-α-PAT] has been used for the spectrophotometric determination of Cu(II). The method is simple, rapid and sensitive. Light green colour 1:2 (M:L) complex formed between Cu(II) and DHB-α-PAT in the pH range 3.0-6.5. The absorption spectrum shows as shoulder at 420 nm. The molar absorptivity and Sandell’s sensitivity is found to be 5.018 x103lit.mol-1.cm-1 and 0.01266 µg/cm2, respectively. A number of foreign ions are tested for their interference. Antibacterial activity, TGA studies, Elemental analysis, 1H1 NMR spectra of Reagent, IR spectra of the reagent and its complex were reported. The reagent has been successfully applied to the determination of Cu(II) in drained microetch solution.
