3,3'-Diaminobenzidine Usage And Synthesis
Description3,3'-Diaminobenzidine (DAB) is a precursor to polybenzimidazole. DAB is frequently used in the immunohistochemical staining of nucleic acids and proteins. It can also be used to detect fingerprints in blood because that it can be oxidized by hydrogen peroxide in the presence of hemoglobin to give a dark-brown color.
Chemical PropertiesOff-white to brown solid.
Uses3,3'-Diaminobenzidine is used as peroxidase substrate and a reagent for spectrophotometric determination of selenium. DAB is used for the immunohistochemical staining of nucleic acids and proteins. As a dark brown dye, was used as an antibody-specific stain to identify the paired antibodies in breast tissue. It may be used for the synthesis of a useful, linear, Schiff-base coordination polymer.
Synthesis3,3'-Diaminobenzidine can be synthesized by treating 3, 3'-dichlorobenzidine with ammonia in the presence of copper catalyst at high temperature and pressure.
Application3,3'-Diaminobenzidine is used for preparation of high-strength material such as nucleic acid stain and resistance high-temperature polymers such as bullet-proof vests.?
DefinitionChEBI: 3,3'-diaminobenzidine is a member of the class of biphenyls that is benzidine in which one of the hydrogens ortho to each of the amino groups has been replaced by an amino group. It has a role as a histological dye. It is a member of biphenyls and a substituted aniline.
General Description3,3'-Diaminobenzidine tetrahydrochloride hydrate is an organic compound used as a peroxidase substrate.
Biochem/physiol ActionsDAB (3,3′-Diaminobenzidine) is utilized in many applications for the visualization of peroxidase activity. In the peroxidase reaction, DAB serves as a hydrogen donor in the presence of peroxide. The oxidized DAB forms an insoluble brown end-product for use in the immunohistological and immunoblotting staining procedures.
Safety ProfileSuspected carcinogen withexperimental tumorigenic data. Moderately toxic byingestion. Mutation data reported. When heated todecomposition it emits toxic fumes of NOx.
