Specification

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.
