Usage

Description

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.

Chemical Properties

Off-white or grey tablets

Uses

Different sources of media describe the Uses of 20325-40-0 differently. You can refer to the following data:
1. 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.
2. It is suitable for use in ELISA procedures. In neurohistochemistry o-Dianisidine dihydrochloride has demonstrated perikaryal labeling as well as retrograde and anterograde transport to the primary olfactory cortex. It has also been used for a paper based-micro fluidic device to semi-quantitatively measure lactate, uric acid, and glucose. 3,3'-Dimethoxybenzidine is used principally as an intermediate in the production of commercial bisazobiphenyl dyes for coloring textiles, paper, plastic, rubber, and leather.
