4,4'-DIMETHOXYDIPHENYLAMINE Chemical Properties,Usage,Production

Chemical Properties

silver-grey crystalline solid

Uses

4,4'-Dimethoxydiphenylamine is a diphenylamine derivative used as a chemical additive for cured rubber. It is used in the synthesis of amine electron donating groups in organic donor-bridge-acceptor dyads in Dye Sensitized Solar Cells (DSSC). 4,4?-Dimethoxydiphenylamine is an electron donor and used in the synthesis of organic nonlinear optical (NLO) chromophores which exhibit high thermal and chemical stability, high degree of non-linearity and transparency. They are used in high performance photonic devices.

General Description

Fine very light gray to silver-gray crystalline solid.

Air & Water Reactions

4,4'-DIMETHOXYDIPHENYLAMINE may be sensitive to prolonged exposure to air. Slowly oxidized. Insoluble in water.

Reactivity Profile

4,4'-DIMETHOXYDIPHENYLAMINE 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.

Health Hazard

ACUTE/CHRONIC HAZARDS: 4,4'-DIMETHOXYDIPHENYLAMINE can produce extremely irritating fumes when exposed to air or fire.

Fire Hazard

Flash point data for 4,4'-DIMETHOXYDIPHENYLAMINE are not available. 4,4'-DIMETHOXYDIPHENYLAMINE is probably combustible.
