Heracleum sphondylium

Heptanoic acid, also known as enanthic acid, is a carboxylic acid with the chemical formula CH3(CH2)5COOH. It is a colorless, oily liquid with an unpleasant, rancid odor. It is classified as a medium-chain fatty acid and is used in the preparation of esters for the perfume industry and as an intermediate in the manufacture of pharmaceuticals, synthetic flavors, and other chemical products.

Chemical Properties

Heptanoic acid is a saturated fatty acid that consists of seven carbon atoms, hence the prefix "hepta-" in its name. It has a molar mass of 130.19 g/mol and a density of 0.918 g/cm3. It is soluble in water and most organic solvents, and it has a boiling point of 223 °C (433 °F) and a melting point of -10.5 °C (13.1 °F).

Production

Heptanoic acid can be produced by the oxidation of heptanol or by the hydrolysis of heptanoate esters. It can also be synthesized from petroleum products through a series of chemical reactions.

Uses

Heptanoic acid is primarily used in the production of esters for the perfume and flavor industries. It is also used as an intermediate in the manufacture of pharmaceuticals, synthetic flavors, and other chemical products. In addition, it is used as a flavoring agent in certain foods and beverages.

Safety

Heptanoic acid is not considered highly toxic, but it can cause irritation to the skin and eyes. It is also harmful if swallowed or inhaled in large amounts. Proper safety measures should be taken when handling this chemical.
