Metabolite Identification
Common NameHeptanoic acid
DescriptionHeptanoic 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. It contributes to the odor of some rancid oils. It is slightly soluble in water, but well soluble in ethanol and ether.
