General Description
Red needle-like crystals or dark brown granular solid.
Reactivity Profile
2-AMINOANTHRAQUINONE(117-79-3) may react with strong oxidizing agents. Forms salts with mineral acids. Can be acylated or alkylated on the nitrogen atom and nitrated or sulgonated in the ring .
Air & Water Reactions
Insoluble in water.
Hazard
Questionable carcinogen.
Health Hazard
ACUTE/CHRONIC HAZARDS: This compound may be absorbed through the skin and may cause irritation. It is a positive animal carcinogen. When heated to decomposition this material emits toxic fumes of carbon monoxide, carbon dioxide and nitrogen oxides.
Potential Exposure
2-Aminoanthraquinone is used as a dye intermediate; in the industrial synthesis of anthraquinone and pharmaceuticals. It is the precursor of five dyes and one pigment, including Color Index Vat Blues 4, 6, 12, and 24; Vat Yellow 1; and Pigment Blue 22. Because AAQ is used on a commercial scale solely by the dye industry, the potential for exposure to the compound is greatest for workers at dye manufacturing facilities. However, no additional data are available on the number of facilities using AAQ. The Consumer Product Safety Commission staff believes that trace amounts of unreacted AAQ may possibly be present in some dyes based on this chemical and in the final consumer product. Exposure even to trace amounts may be a cause for concern. This concern is based on experience with other dyes derived from aromatic amines.
Fire Hazard
Flash point data for this compound are not available; however, 2-AMINOANTHRAQUINONE is probably combustible.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Definition
ChEBI:2-Aminoanthraquinone is an anthraquinone.
Synthesis
Older methods used
anthraquinone-2-sulfonic acid as the starting
material, replacing the SO3H group. The preferred
method is replacement of the chlorine in
2-chloroanthraquinone , .
Carcinogenicity
2-Aminoanthraquinone is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
