General Description

Green plates with bluish luster or a black powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

4-NITROSODIPHENYLAMINE 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. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. May react with strong oxidizing agents .

Hazard

Questionable carcinogen.

Fire Hazard

Flash point data for 4-NITROSODIPHENYLAMINE are not available; however, 4-NITROSODIPHENYLAMINE is probably combustible.

Safety Profile

Poison by intravenous route. Suspected carcinogen with experimental carcinogenic and neoplastigenic data. Moderately toxic by ingestion. Mutation data reported. An eye irritant. When heated to decomposition it emits toxic fumes of NOx. See also NNITROSO COMPOUNDS and AMINES.

Potential Exposure

Used as a chemical intermediate for dyes and pharmaceuticals; in making monomers; and vulcanizing rubber.

Shipping

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard Class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

Purification Methods

The amine forms dark green crystals from EtOH or *C6H6 (m 143o). It has UV at max 421nm (EtOH) and is used for detecting Pd and Rh. It is highly toxic and a possible carcinogen.[Beilstein 12 H 207, 12 II 122, 12 III 347, 12 IV 1860..]

Incompatibilities

Nitrated organics range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction. Reaction with aliphatic amines can release carcinogenic nitrosamines. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. 4-nitrosodiphenylamine 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. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrideds and active metals. May react with strong oxidizing agents.
