3,3'-Dihydroxybenzidine Usage And Synthesis
Chemical PropertiesA pale brown solid
Uses4,4'-diaminobiphenyl-3,3'-diol is used as organic intermediates.
Uses3,3''-Dihydroxybenzidine is used in preparation method of covalent organic framework-based metamaterial for optical device.
General DescriptionColorless crystals.
Air & Water ReactionsKeep well closed. Protect from air and light.
Reactivity Profile3,3'-Dihydroxybenzidine is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
Health HazardACUTE/CHRONIC HAZARDS: When heated to decomposition 3,3'-Dihydroxybenzidine emits toxic fumes.
Safety ProfileSuspected carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of Nox
