3,3′-Diaminobenzidine tetrahydrochloride

Description:
3,3′-Diaminobenzidine tetrahydrochloride (DAB) is an organic compound commonly used as a chromogen in immunohistochemistry and as a reagent in various chemical reactions. It appears as a dark brown to black crystalline powder and is soluble in water, which facilitates its application in biological staining. DAB is known for its ability to produce a colored precipitate upon oxidation, making it valuable for visualizing proteins and other biomolecules in tissue samples. The compound contains two amino groups, which contribute to its reactivity and ability to form stable complexes with metal ions. However, it is important to note that DAB is considered a potential carcinogen, and appropriate safety measures should be taken when handling it. In laboratory settings, it is typically used in buffered solutions and requires careful storage to maintain its stability. Overall, 3,3′-Diaminobenzidine tetrahydrochloride is a significant tool in biochemical research, particularly in the fields of pathology and molecular biology.
