PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance YELLOW-TO-COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers Chemical dangers Decomposes on contact with strong oxidants, reducing agents, acids or bases. This produces toxic fumes. This generates fire and explosion hazard. Attacks some forms of plastic, rubber and coatings. On combustion, forms nitrogen oxides and carbon monoxide.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. Effects of short-term exposure The substance is irritating to the eyes. The substance may cause effects on the blood. This may result in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.	Inhalation risk A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure The substance may have effects on the liver, blood and testes. This substance is probably carcinogenic to humans. May cause heritable genetic damage to human germ cells. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
