Nitrobenzene
Nitrobenzene is an organic compound with the chemical formula C6H5NO2. It is a yellowish, oily, aromatic nitro-compound with an almond-like odor that emits toxic fumes of nitrogen oxides upon combustion. Nitrobenzene is primarily used in the manufacture of aniline, but is also used in the manufacture of lubricating oils, dyes, drugs, pesticides and synthetic rubber. It is also used to mask unpleasant odors in shoe and floor polishes, leather dressings, paint solvents, and other materials. It had been used as an inexpensive perfume for soaps also.
Exposure to nitrobenzene irritates the skin, eyes and respiratory tract and can result in methemoglobinemia causing fatigue, dyspnea, dizziness, disturbed vision, shortness of breath, collapse and even death. Nitrobenzene also damages the liver, spleen, kidneys and central nervous system.
