Hendecanoic

Hendecanoic refers to a chemical structure containing eleven carbon atoms. In organic chemistry, this prefix is most commonly associated with acids and their derivatives. Hendecanoic acid, also known as undecanoic acid, is a saturated fatty acid with the chemical formula CH3(CH2)9COOH. It is a white crystalline solid at room temperature and has a characteristic waxy odor.

Hendecanoic acid occurs naturally in various sources, including milk fat and coconut oil, though typically in smaller quantities compared to other fatty acids. It can also be produced synthetically. Its applications are diverse. It is used in the manufacturing of perfumes, cosmetics, and soaps due to its emollient and fragrance properties. In the pharmaceutical industry, undecanoic acid and its derivatives, such as undecylenate salts, are employed for their antifungal properties, often found in topical treatments for skin infections like athlete's foot. The chemical can also serve as a precursor in the synthesis of other organic compounds and polymers. Its esters are utilized as plasticizers and lubricants.
