Description and Uses
Heptanal has a very strong, fatty, harsh, pungent odor and an unpleasant, fatty taste. Heptanal is obtained by distilling castor oil, preferably under reduced pressure.
Heptanal is used as a synthesis intermediate in the fragrances and flavors industry. It is the precursor to 1-heptanol, ethyl heptanoate and for certain lubricants.
