About C7H14O2 (Enanthic acid)

Enanthic acid is a saturated fatty acid with a seven-carbon chain. It is a colorless oily liquid with an unpleasant, rancid odor. Naturally occurring in some plant oils, it is used in the synthesis of esters for fragrances and flavors. Industrially, enanthic acid serves as an intermediate in the production of lubricants and plasticizers. Chemical formula: CH₃(CH₂)₅COOH

Other names: enanthic_acid, C7H14O2, Enanthic acid, C₇H₁₄O₂, Heptanoic acid, n-Heptanoic acid, Oenanthic acid, Enanthylic acid, Heptylic acid
