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.
