This azoic coloring can be reduced in para-phenylenediamine
(PPD). It can be found in some semi-permanent
hair dyes and patch tests are frequently positive
(about 30%) in hairdressers with hand dermatitis.
Because of hydrolysis of the azo bond, the detection of
sensitization to p-aminoazobenzene may be assumed
by a PPD test. | [CAS DataBase Reference]

powder | [Definition]
ChEBI: Azobenzene substituted at one of the 4-positions by an amino group. | [Uses]
In form of its salts in dyeing; intermediate in manufacture of Acid Yellow, diazo dyes and indulines. | [General Description]
Odorless brownish-yellow needles with bluish coating, or an orange powder. | [Reactivity Profile]
4-AMINOAZOBENZENE(60-09-3) can detonate, particularly if sensitized by the presence of metal salts or strong acids. May form toxic gases with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. May form flammable gases with alkali metals. May react explosively with strong oxidizing agents, metal salts, peroxides, and sulfides. Emits toxic fumes of oxides of nitrogen when heated to decomposition (over 350°C) [Sax, 2nd ed., 1965, p. 417]. | [Air & Water Reactions]
Dust may form an explosive mixture in air. Insoluble in water. | [Hazard]
Possible carcinogen. | [Potential Exposure]
An azo compound used in form of salts in dyeing; used as intermediate in manufacture of acid yellow and diazo dyes; in insecticides, waxes, lacquers, varnishes, stains, styrene resins | [Fire Hazard]
Flash point data for this chemical are not available; however, 4-AMINOAZOBENZENE is probably combustible. | [First aid]
Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. | [Shipping]

Dust may form explosive mixture with air. Azo compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. This chemicalis sensitive to prolonged exposure to heat. This chemical is incompatible with strong oxidizing agents | [Description]
This azoic coloring can be reduced in paraphenylenediamine
(PPD). It ean be found in some semipermanent
hair dyes, and patch tests are frequently
positive (about 30%) in hairdressers with hand
dermatitis. Because of cross-sensitivity, the detection
of sensitization to p-aminoazobenzene may be assumed
by a PPD test.
| [Preparation]
commonly known as Aniline Yellow. (a) aniline?hydrochloride solution added to a aniline?diazonium salt, and slowly, until aniline?diazonium salt salt disappear so far. Then in contain a small amount of aniline?hydrochloride aniline?solution will product (Diazoaminobenzene) 30 ~ 40 ℃ heating 2 ~ 3 hours,??acidified to form 4-(Phenyldiazenyl)benzenamine??hydrochloride and crystalline precipitates. In order to obtain 4-(Phenyldiazenyl)benzenamine?times the company, and then 4-(Phenyldiazenyl)benzenamine hydrochloride dissolved in water and mercerized. (B) aniline?diazotization and coupling anilino-methanesulfonic acid, sodium hydroxide solution and then with boiled together, hydrolyzed mesylate. | [Properties and Applications]
green light yellow to red light yellow. Melting point is 127.5 ℃, its hydrochloride for blue crystal. Soluble in ethanol, slightly soluble in water for yellow. In concentrated sulfuric acid for brown, red after diluted solution; In hydrochloric acid solution for red, boil color disappear. Used for alcohol soluble paint, varnish, paraffin wax, oil, synthetic resin coloring.
