Hazard InformationBack Directory
[General Description]

Yellow crystalline powder or yellow needles.
[Reactivity Profile]

C.I. SOLVENT YELLOW 34 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.
[Hazard]

Confirmed carcinogen.
[Health Hazard]

Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution.
[Potential Exposure]

Auramine is used industrially as a dye or dye intermediate for coloring textiles; paper, and leather. Also used as an antiseptic (a powerful antiseptic in ear and nose surgery, and treatment of gonorrhea) and fungicide. Human exposure to auramine occurs principally through skin absorption or inhalation of vapors. Low-level dermal exposure to the consumer may occur but would be limited to any migration of auramine from fabric, leather, or paper goods.
[Fire Hazard]

Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.
[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.

[Incompatibilities]

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.
[Description]

Auramine is a yellow crystalline powder or flaky material. Molecular weight= 267.4; Freezing/Meltingpoint=136℃. Hazard Identification (based on NFPA-704M Rating System): Health 3, Flammability 1, Reactivity 0;(hydrochloride) Health 3, Flammability 0, Reactivity 0.Insoluble in water.
[Chemical Properties]

Auramine is a yellow crystalline powder or flaky material.
[Waste Disposal]

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Incinerate in furnace with afterburner and scrubber.
[Definition]

ChEBI: A member of the class of imines that is benzophenone imine carrying two dimethylamino substituents at positions 4 and 4'. The hydrochloride salt is the biological stain 'auramine O'
[Preparation]

(a) will Sulphur dissolved in 4-(4-(Dimethylamino)benzyl)-N,N-dimethylbenzenamine?methane. Add in ammonia and sodium chloride, ammonia in 175 ℃ heat the mixture, with hot water extraction dye and salting out (GP53614); (b) Bis (4 – (dimethylamino) phenyl) methanone and ammonia and Zinc chloride in a total of 150 ~ 160 ℃ heat (GP 29060). Free base is to add the same amount of naoh aqueous solution hydrochloride, sodium carbonate and ammonia and have to.
[Agricultural Uses]

Fungicide: Auramine is used industrially as a dye or dye intermediate for coloring textiles, paper, and leather. Also used as an antiseptic (a powerful antiseptic in ear and nose surgery and in gonorrhea treatment)

[storage]

Color Code—Blue: Health Hazard/Poison: Store ina secure poison location. Prior to working with auramineyou should be trained on its proper handling and storage.Store in tightly closed containers in a cool, well-ventilatedarea away from oxidizers. Sources of ignition, such as smoking and open flames, are prohibited where this chemical isused, handled, or stored in a manner that could create apotential fire or explosion hazard. A regulated, marked areashould be established where this chemical is handled, used,or stored in compliance with OSHA Standard 1910.1045.
[Properties and Applications]

brilliant green yellow. Soluble in cold water, soluble in hot water for brilliant yellow, boils part decomposition, soluble in ethanol for yellow. In concentrated sulfuric acid to colorless, dilution after buff. The dye for C.I. Basic Yellow 2 free base. Used for oil, paraffin wax, alcohol solvent, alcohol soluble paint, printing ink color.
