Safety Profile
Suspected carcinogen. Moderately toxic by ingestion, intravenous, subcutaneous, intramuscular, and intraperitoneal routes. Mildly toxic by skin contact and inhalation. Experimental teratogenic and reproductive effects. A skin and severe eye irritant. Human mutation data reported. Flammable liquid when exposed to heat or flame; can react with oxidzing materials. Explosion hazard when exposed to flame. Explosive reaction with bromine, potassium permanganate, triethylaluminum + heat. Forms explosive mixtures with lithium azide (shock-sensitive above 2OO0C), uranium perchlorate. Igrution on contact with chromium trioxide. Violent reaction with chlorine, sodium hydroborate + heat, dusocyanatomethane, carbon tetrachloride + iron, 1,2,3,4,5,6 hexachlorocyclohexane + iron. Vigorous exothermic reaction with magnesium nitrate, sodum + heat, sodium hydride + heat, sulfinyl chloride + traces of iron or zinc, 2,4,6-trichloro-l,3,5-triazine (with gas evolution), and many other materials. Avoid contact with halogenated hydrocarbons, inorganic and organic nitrates, (2,5-diethyl pyrrole + P(OCl)3), cGCl6, methylene dusocyanates, P203. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx
