3,3'-Diaminobenzidine Usage And Synthesis
Description 3,3'-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. It can be prepared by treating 3, 3’-dichlorobenzidine with ammonia in the presence of copper catalyst at high temperature and pressure.
Chemical Properties solid
Uses Nucleic acid stain.
Uses 3,3',4,4'-biphenyltetramine be used for preparation of high-strength material and resistance high-temperature polymers such as bullet-proof vests.
Definition ChEBI: 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member of the class of biphenyls that is benzidine in which one of the hydrogens ortho to each of the amino groups has been replaced by an amino group.
