Caprylic acid

Common card · No. 360364

Caprylic acid (from Latin capra 'goat'), also known under the systematic name octanoic acid or C8 acid, is a saturated fatty acid, medium-chain fatty acid (MCFA). It has the structural formula H3C−(CH2)6−COOH, and is a colorless oily liquid that is minimally soluble in water with a slightly unpleasant rancid-like smell and taste. Salts and esters of octanoic acid are known as octanoates or caprylates. The name of the related acyl group is octanoyl, capryloyl, or caprylyl. It is a common industrial chemical, which is produced by oxidation of the C8 aldehyde. Its compounds are found naturally in the milk of various mammals and as a minor constituent of coconut oil and palm kernel oil. Two other acids are named after goats via the Latin word capra: caproic acid (C6) and capric acid (C10). Together, these three fatty acids comprise 15% of the fatty acids in goat milk fat.
