2,3-butanedione usage and synthesis

chemical properties	liquid with a butter-like odour
usage	inactivates aminopeptidase-n.1 cyclocondensation with amines has been used to form triazine2 and pteridine ring systems.3 also used as a precursor to α-diones.4
general description	a clear colorless liquid with a strong chlorine-like odor. flash point 80°f. less dense than water. vapors heavier than air.
air & water reactions	highly flammable. soluble in water.
reactivity profile	2,3-butanedione is a flammable liquid, b.p. 88° c, moderately toxic. when heated to decomposition 2,3-butanedione emits acrid smoke and fumes [sax, 9th ed., 1996, p. 544].
health hazard	inhalation or contact with material may irritate or burn skin and eyes. fire may produce irritating, corrosive and/or toxic gases. vapors may cause dizziness or suffocation. runoff from fire control may cause pollution.
fire hazard	highly flammable: will be easily ignited by heat, sparks or flames. vapors may form explosive mixtures with air. vapors may travel to source of ignition and flash back. most vapors are heavier than air. they will spread along ground and collect in low or confined areas (sewers, basements, tanks). vapor explosion hazard indoors, outdoors or in sewers. runoff to sewer may create fire or explosion hazard. containers may explode when heated. many liquids are lighter than water.
