Tetramethylbenzidine Usage And Synthesis

Chemical Properties White or light yellow solid
General Description Pale yellow crystals or off-white powder.
Air & Water Reactions Insoluble in water.
Reactivity Profile Tetramethylbenzidine is sensitive to prolonged exposure to light . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Fire Hazard Flash point data for Tetramethylbenzidine are not available, however, Tetramethylbenzidine is probably combustible.
