3,3′-Diaminobenzidine

Description:

3,3′-Diaminobenzidine (DAB) is an organic compound characterized by its structure, which features two amino groups attached to a benzidine backbone. It is a pale yellow to brown crystalline solid that is soluble in water and various organic solvents. DAB is primarily used as a chromogen in immunohistochemistry and as a reagent in various chemical reactions, particularly in the detection of peroxidase activity. The compound exhibits strong reducing properties due to the presence of the amino groups, making it useful in various analytical applications. However, it is important to note that DAB is considered a potential carcinogen and poses health risks upon exposure, necessitating careful handling and appropriate safety measures in laboratory settings. Additionally, it can undergo oxidation to form a colored polymer, which is utilized in staining techniques. Overall, 3,3′-Diaminobenzidine is a valuable chemical in research and diagnostic applications, but its toxicity requires caution in its use.

3,3'-Diaminobenzidine

CAS: 91-95-2

3,3'-Diaminobenzidine (DAB) is an organic compound derived from benzidine. It is the precursor to the synthetic fibre polybenzimidazole (PBI), which have high thermal and oxidative stability properties. DAB is water-soluble as the tetrahydrochloride salt and is used in immunohistochemical staining of nucleic acids and proteins. Research in Alzheimer's disease, Aβ protein amyloid plaques are targeted by a primary antibody, and subsequently by a secondary antibody, which is conjugated with a peroxidase enzyme. This will bind DAB as a substrate and oxidize it, producing an easily observable brown colour. 3,3’-Diaminobenzidine is also available as the tetrahydrochloride salt and the tetrahydrochloride hydrate.
