Useful:

• Chemical Classes: Nitrogen Compounds -> Nitros, Aliphatic
• Canonical SMILES: C[N+](=O)[O-]
• Inhalation Risk: A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20 °C.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. This may result in central nervous system depression.
• Effects of Long Term Exposure: Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the peripheral nervous system, kidneys and liver. This may result in impaired functions.
• Description: Nitromethane (75-52-5) is an explosive material that was originally manufactured for various applications including mining, construction, demolition, law enforcement, and military uses. However, due to threats of terrorism and increased attention to accident prevention, regulations concerning the transportation, storage, use, and transfer relating to explosives have steadily increased over the last few years and manufacturing limited.
• Physical properties: Colorless liquid with a strong, disagreeable odor. Odor threshold concentration is 3.5 ppm (quoted, Amoore and Hautala, 1983).
• Uses: Most of the nitromethane produced in the United States (85% to 90%) is used in the synthesis of nitromethane derivatives used as pharmaceuticals, agricultural soil fumigants, and industrial antimicrobials (Markofsky 1991, Angus 2001). Nitromethane also is used as a fuel or fuel additive with methanol in racing cars, boats, and model engines. It formerly was used in the explosives industry as a component in a binary explosive formulation with ammonium nitrate and in shaped charges, and it was used as a chemical stabilizer to prevent decomposition of various halogenated hydrocarbons (NTP 1997, IARC 2000, Angus 2001). Solvent; chemical synthesis; fuel for professional and model racing cars; in explosive mixtures Rocket fuel; solvent for zein. Used in the coating industry.
