General description

3-(2-Pyridyl)-5,6-diphenyl-1,2,4-triazine (PDT) reacts with Cu(II) perchlorate in ethanol to yield [Cu(PDT)2(ClO4)2].

Application

3-(2-Pyridyl)-5,6-diphenyl-1,2,4-triazine was employed as chromogenic-extraction reagent during spectrophotometric determination of iron in acids and acidic solutions. It was also employed as precolumn derivatizing reagent in the HPLC method with UV absorbance detection for the Fe(II) determination.
