3,3-DIAMINO BENZIDINE (purified) is a product provided by Research-Lab Fine Chem Industries. Laboratory reagents are chemicals which are used in laboratories as a part of experimental procedures. These reagents can be important parts of chemical reactions, analytical reagents or starting material for the production of other materials.

This 3,3-DIAMINO BENZIDINE is purified. The reagent is available as a powder which is soluble in water. It has a melting point of 175 to 177 C. 3,3'-Diaminobenzidine can be generated by treating 3,3'-dichlorobenzidine with ammonia, with a copper catalyst at high temperature and pressure, followed by acidic workup. While it is stable under general conditions, this reagent is incompatible with strong oxidizing agents. 3,3'-Diaminobenzidine has a variety of applications in chemical and biological sectors.

This compound finds several applications in the synthesis of various organic derivatives.

3,3'-Diaminobenzidine is majorly used as a precursor to polybenzimidazole, which forms fibers that are famous for its chemical and thermal stability.

This compound is oxidized in the presence of hemoglobin by hydrogen peroxide to give a dark-brown color, which is utilized in forensic applications.

It is similarly used in the immunohistochemical staining of nucleic acids and proteins.

This reagent is suitable for the industrial synthesis of products and research applications.
