heptane usage and synthesis

chemical properties colourless liquid

usage suitable for hplc, spectrophotometry, environmental testing

general description clear colorless liquids with a petroleum-like odor. flash point 25°f. less dense than water and insoluble in water. vapors heavier than air.

air & water reactions highly flammable. insoluble in water.

reactivity profile heptane is incompatible with the following: strong oxidizers .

health hazard vapor: not irritating to eyes, nose or throat. if inhaled, will cause coughing or difficult breathing. liquid: irritating to skin and eyes. if swallowed, will cause nausea or vomiting.

fire hazard flammable. flashback along vapor trail may occur. vapor may explode if ignited in an enclosed area.
