Origin: Formed within English, by compounding. Etymons: octane n., -oic comb. form.

Etymology: < octane n. + -oic comb. form. Compare earlier octoic adj.

Chemistry.

octanoic acid n. any saturated fatty acid of the formula C₇H₁₅COOH, of which several isomers exist; spec. (also n-octanoic acid) the straight-chain primary acid, CH₃(CH₂)₆COOH, a liquid (also called caprylic acid), glycerides of which are present in butter and many other fats.
