A new class of bromo substituted o-hydroxy oximes and thiosemicarbazones have been prepared by using Resorcinol and characterized on the basis of elemental, IR and UV spectral studies. The ligands 2-Hydroxy-4-n-propoxy-5-bromoacetophenone oxime (HnPBAO) and 4-phenyl-3-thiosemicarbazone of 2-hydroxy-4-n-propoxy-5-bromoacetophenone (HnPBAPT) formed, act as an organic chelating reagent for the rapid determination of transition metal ions spectrophotometrically. Both ligands obtained were selective and sensitive.
