CAS 91-95-2: 3,3′-Diaminobenzidina
Descripción:
3,3′-Diaminobenzidina (DAB) es un compuesto orgánico caracterizado por su estructura, que presenta dos grupos amino unidos a un esqueleto de benzidina. Es un sólido cristalino de color amarillo pálido a marrón que es soluble en agua y en varios disolventes orgánicos. El DAB se utiliza principalmente como cromógeno en inmunohistoquímica y como reactivo en diversas reacciones químicas, particularmente en la detección de actividad de peroxidasa. El compuesto exhibe fuertes propiedades reductoras debido a la presencia de los grupos amino, lo que lo hace útil en diversas aplicaciones analíticas. Sin embargo, es importante señalar que el DAB se considera un posible carcinógeno y presenta riesgos para la salud al ser expuesto, lo que requiere un manejo cuidadoso y medidas de seguridad adecuadas en entornos de laboratorio. Además, puede sufrir oxidación para formar un polímero coloreado, que se utiliza en técnicas de tinción. En general, 3,3′-Diaminobenzidina es un químico valioso en aplicaciones de investigación y diagnóstico, pero su toxicidad requiere precaución en su uso.

CAS:3,3'-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. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

CAS: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.Fórmula:C12H14N4Pureza:Min. 98 Area-%Forma y color:PowderPeso molecular:214.27 g/mol3,3′-Diaminobenzidine
