heptaldehyde usage and synthesis

chemical properties	colourless liquid
usage	labelled heptanal. bioconversion of heptanal to heptanol by saccharomyces cerevisiae and effect of c source maltose.
general description	a colorless, oily liquid with a penetrating fruity odor. insoluble in water and less dense than water. hence floats on water. flash point near 141°f. used to make perfumes and pharmaceuticals.
air & water reactions	flammable. insoluble in water.
reactivity profile	heptaldehyde may undergo exothermic self-condensation or polymerization reactions in the presence of acids. may generate flammable and/or toxic gases with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. is readily oxidized to give heptanoic acid. can react with air to give first peroxo acids, and ultimately heptanoic acid. these autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). the presence of stabilizers (antioxidants) retards autoxidation. incompatible with strong oxidizers, bases and reducing agents.
health hazard	may cause toxic effects if inhaled or absorbed through skin. inhalation or contact with material may irritate or burn skin and eyes. fire will produce irritating, corrosive and/or toxic gases. vapors may cause dizziness or suffocation. runoff from fire control or dilution water 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.
