Community Right-To-Know List. EPA Genetic Toxicology Program. Reported in EPA TSCA Inventory.

Confirmed carcinogen with experimental carcinogenic, tumorigenic, and teratogenic data. Poison by intraperitoneal route. Moderately toxic by ingestion and inhalation. Human systemic effects by inhalation: anorexia, hypermotility, diarrhea, nausea or vomiting. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. Can cause liver and kidney injury, methemoglobinemia, and cyanosis. Very dangerous fire hazard when exposed to heat, open flame, or oxidizers. May explode on heating. Violent reactions with chlorosulfonic acid, oleum. May react with amines + heavy metal oxides (e.g., mercury oxide or silver oxide) to form explosive salts. May ignite on contact with mixtures of carbon + hopcalite, which are used in some respirators. Hopcalite is a catalyst consisting of coprecipitated copper(II) oxide and manganese(IV) oxide. To fight fire, use alcohol foam, CO₂, dry chemical, water spray. When heated to decomposition it emits toxic fumes of NO_x.

2-Nitropropane (CAS NO.79-46-9) is colorless liquid with a mild fruity odor. It may float on or sink in water.It is highly flammable.It is sensitive to heat. Can react with amines/heavy metal oxides, strong acids, strong alkalis, and chlorosulfonic acid. . The heat of adsorption of 2-Nitropropane on carbon, such as that found in cartridge respirators, is extremely high. Metal oxide catalysts, such as copper oxide or manganese oxide, can initiate ignition, therefore carbon respirators should not be used in environments that have a high vapor concentration of 2-Nitropropane.It causes respiratory tract irritation, headache, dizziness, nausea, and diarrhea. Ingestion causes irritation of mouth and stomach. Contact with liquid irritates eyes and causes mild irritation of skin. Toxic oxides of nitrogen may form in fire.
