Heptanoic acid, also called enanthic acid, is an organic compound composed of a seven-carbon chain terminating in a carboxylic acid. It is an oily liquid with an unpleasant, rancid odor.[1] It contributes to the odor of some rancid oils. It is slightly soluble in water, but very soluble in ethanol and ether.

Production

Ricinoleic acid is the main precursor to heptanoic acid.

The methyl ester of ricinoleic acid, obtained from castor bean oil, is the main commercial precursor to heptanoic acid. It is pyrolyzed to the methyl ester of 10-undecenoic acid and heptanal, which is then air oxidized to the carboxylic acid. Approximately 20,000 tons were consumed in Europe and US in 1980.[2]

Uses

Heptanoic acid is used in the preparation of esters, such as ethyl heptanoate, which are used in fragrances and as artificial flavors. Heptanoic acid is used to esterify steroids in the preparation of drugs such as testosterone enanthate, trenbolone enanthate, drostanolone enanthate, and methenolone enanthate (Primobolan).

The triglyceride ester of heptanoic acid is the triheptanoin, which is used in certain medical conditions as a nutritional supplement.
