Disclosed is a novel diagnostic reagent system for the detection of hydroperoxides or substances which react with peroxidatively active substances resulting in the liberation of hydroperoxides which reagent system comprises a chromogenic oxidation indicator and a peroxidase or a peroxidatively active substance, together with an inhibitor of color generation selected from the group of 1,4-disubstituted semicarbazides, thiosemicarbazides and 1,5-disubstituted carbazides as inhibitors of color generation. By inhibiting the generation of color formed by oxidation of the chromogenic indicator, the indicator's usefulness in discriminating between varying concentrations of analyte is enhanced.

The solvent effect on the electronic spectra of di(4-bromophenyl)carbazone and its Cu(II), Zn(II), Cd(II) complexes have been studied by synthesizing and characterizing them by magnetic moment, IR, EPR and 1H NMR spectral measurements. The electric dipolemoments of these compounds in the first electronically excited state have been determined. The results indicate that the observed band systems in
