Nonanoic acid (MF: C9H18O2, MW: 158.24) is a colorless to pale yellow oily liquid with a characteristic fatty odor; it is a nine-carbon saturated fatty acid. It exhibits the typical chemical properties of a carboxylic acid and serves as an important fine chemical raw material in fields such as organic synthesis intermediates, food flavorings, paint drying agents, plasticizers, and herbicides. It occurs naturally in essential oils such as rose, geranium, and iris, and can also be produced through chemical synthesis.
