Description and Uses
o-Dianisidine (dihydrochloride) is a colorimetric peroxidase substrate that has been used as a substrate to semi-quantitatively measure lactate, uric acid , and glucose. It has also been used as a reagent for the detection of various metals, thiocyanates, and nitrites. This aromatic amine is initially colorless but turns to violet upon oxidization and is spectrophotometrically measured at a wavelength of 405 nm.
o-Dianisidine (3,3′-dimethoxybenzidine) has been used as a component of GO (glucose oxidase) reagent, which is used for measuring the glucose content. It has also been used as a substrate to measure myeloperoxidase activity.
