3,3'-Diaminobenzidine tetrahydrochloride dihydrate

Description:
3,3'-Diaminobenzidine tetrahydrochloride dihydrate is a chemical compound primarily used as a chromogenic substrate in various biochemical assays, particularly in immunohistochemistry for the detection of peroxidase activity. It is a derivative of benzidine, characterized by the presence of two amino groups attached to the benzene rings, which enhances its reactivity. This compound appears as a dark brown to black solid and is soluble in water, forming a stable solution. The tetrahydrochloride form indicates that it is a salt, with four hydrochloride ions associated with the diamine base, contributing to its solubility and stability in aqueous environments. As a dihydrate, it contains two molecules of water, which are integral to its crystalline structure. While it is useful in laboratory settings, safety precautions are necessary due to the potential toxicity and carcinogenicity associated with benzidine derivatives. Proper handling and disposal protocols should be followed to mitigate health risks.
