| | 4-NITROSODIPHENYLAMINE Usage And Synthesis |
| Chemical Properties | TKB is a black powder or a green plate-like
material with a bluish luster. | | Chemical Properties | dark blue to black powder | | Uses | 4-?Nitrosodiphenylamine is used in organic synthesis such as in the preparation of 1-(Phenylamino)pseudo-mauveine water soluble dye. Potential mutagenic compound.Environmental toxin on US EPA Toxic Release Inventory list (TRI) list. | | Uses | Has been used as retardant in vulcanizing rubber. | | Definition | ChEBI: Para-Nitrosodiphenylamine is a member of benzenes. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 32, p. 153, 1967 DOI: 10.1021/jo01277a038 | | 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.
