enanthic acid enanthic acid enanthic acid, also called heptanoic acid, is an organic compound composed of a seven-carbon chain terminating in a carboxylic acid functional group. it is a colorless oily liquid with an unpleasant, rancid odor. it contributes to the odor of some rancid oils. it is slightly soluble in water, but very soluble in ethanol and ether. salts and esters of enanthic acid are called enanthates or heptanoates. enanthic acid names preferred iupac name heptanoic acid other names enthanoic acid; enthanylic acid; heptoic acid; heptylic acid; oenanthic acid; oenanthylic acid; 1-hexanecarboxylic acid; c7:0 (lipid numbers) identifiers cas number 111-14-8 y 3d model (jsmol) interactive image chebi chebi:45571 y chembl chembl320358 y chemspider 7803 y drugbank db02938 y echa infocard 100.003.490 kegg c17714 y pubchem cid 8094 unii the3ynp39d y comptox dashboard (epa) dtxsid2021600 inchi inchi=1s/c7h14o2/c1-2-3-4-5-6-7(8)9/h2-6h2,1h3,(h,8,9) ykey: mnwfxjyaoyhmed-uhfffaoysa-n yinchi=1/c7h14o2/c1-2-3-4-5-6-7(8)9/h2-6h2,1h3,(h,8,9)key: mnwfxjyaoyhmed-uhfffaoyap smiles o=c(o)cccccc properties chemical formula c7h14o2 molar mass 130.187 g·mol−1 appearance colorless oily liquid density 0.9181 g/cm3 (20 °c) melting point −7.5 °c (18.5 °f; 265.6 k) boiling point 223 °c (433 °f; 496 k) solubility in water 0.2419 g/100 ml (15 °c) magnetic susceptibility (χ) −88.60·10−6 cm3/mol hazards nfpa 704 (fire diamond) 3 2 0 lethal dose or concentration (ld, lc): ld50 (median dose) 6400 mg/kg (oral, rat) related compounds related compounds hexanoic acid, octanoic acid except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). y verify (what is yn ?) infobox references its name derives from the latin oenanthe which is in turn derived from the ancient greek oinos "wine" and anthos "blossom." production ricinoleic acid is the main precursor to enanthic acid. the methyl ester of ricinoleic acid, obtained from castor bean oil, is the main commercial precursor to enanthic 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. laboratory preparations of enanthic acid include permanganate oxidation of heptanal and 1-octene. uses enanthic acid is used in the preparation of esters, such as ethyl enanthate, which are used in fragrances and as artificial flavors. enanthic 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 enanthic acid is the triheptanoin, which is used in certain medical conditions as a nutritional supplement. safety enanthic acid is toxic if swallowed and corrosive.
