3,3'-Dimethoxybenzidine dihydrochloride Chemical Properties,Usage,Production

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

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.

General Description

Off-white powder.

Air & Water Reactions

Water soluble.

Reactivity Profile

3,3'-Dimethoxybenzidine dihydrochloride 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.

Fire Hazard

Flash point data are not available for 3,3'-Dimethoxybenzidine dihydrochloride, but 3,3'-Dimethoxybenzidine dihydrochloride is probably combustible.

Safety Profile

Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Experimental reproductive data. Mutation data reported.When heated to decomposition it emits very toxic fumes of NO, and HCl.
