2-Naphthylamine

**Semantic type:** Hazardous or Poisonous Substance

**Definition:** A synthetic, air-sensitive, colorless crystalline solid that is soluble in hot water, alcohol, ether and many organic solvents. Currently, it is only used in laboratory research. Because the commercial production and use of 2-naphthylamine are banned, the potential for human exposure is low. The general population may be exposed to this chemical through inhalation of emissions from sources where nitrogen-containing organic matter is burned, such as coal furnaces and cigarettes. At greatest risk of occupational exposure to 2-naphthylamine are laboratory technicians and scientists who use it in research. Acute inhalation exposure to high levels of 2-naphthylamine can result in methemoglobinemia, dyspnea, ataxia, hematuria, dysuria and hemorrhagic cystitis. It is known to be a human carcinogen.
