Hazard Information

General Description

Off-white powder.

Reactivity Profile

3,3'-DIMETHOXYBENZIDINE DIHYDROCHLORIDE(20325-40-0) is an ether substituted acidic organic salt. Reacts weakly as a acid to neutralize bases. May react with strong oxidizing agents or strong reducing agents.

Air & Water Reactions

Water soluble.

Fire Hazard

Flash point data are not available for this chemical, but 3,3'-DIMETHOXYBENZIDINE DIHYDROCHLORIDE is probably combustible.

Description

o-Dianisidine (dihydrochloride) is a colorimetric peroxidase substrate that has been used as a substrate to semi-quantitatively measure lactate, uric acid (Item No. 16219), 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

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.

Uses

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.
