| 3,3'-Dihydroxybenzidine Usage And Synthesis |
| Chemical Properties | A pale brown solid | | Uses | 4,4'-diaminobiphenyl-3,3'-diol is used as organic intermediates. | | Uses | 3,3''-Dihydroxybenzidine is used in preparation method of covalent organic framework-based metamaterial for optical device. | | General Description | Colorless crystals. | | Air & Water Reactions | Keep well closed. Protect from air and light. | | Reactivity Profile | 3,3'-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 Hazard | ACUTE/CHRONIC HAZARDS: When heated to decomposition 3,3'-Dihydroxybenzidine emits toxic fumes. | | Safety Profile | Suspected carcinogen
with experimental carcinogenic,
neoplastigenic, and tumorigenic data.
Mutation data reported. When heated to
decomposition it emits toxic fumes of
