Pelargonic acid, also called nonanoic acid, is an organic compound with structural formula CH 3 (CH 2) 7 CO 2 H. It is a nine-carbon fatty acid. Nonanoic acid is a colorless oily liquid with an unpleasant, rancid odor. It is nearly insoluble in water, but very soluble in organic solvents.
Nonivamide, also called pelargonic acid vanillylamide or PAVA, is an organic compound and a capsaicinoid. It is an amide of pelargonic acid (n-nonanoic acid) and vanillyl amine . It is present in chili peppers , [ 2 ] but is commonly manufactured synthetically.
Among the 250 known harmful chemicals in tobacco smoke, at least 69 can cause cancer." [ 7 ] [ 2 ] [ 8 ] [ 9 ] See: Health effects of tobacco smoking and List of cigarette smoke carcinogens . Although many of these additives are used in making cigarettes, each cigarette does not contain all of these additives.
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
Pseudomonic acid A is the product of an esterification between the 17C polyketide monic acid and the 9C fatty acid 9-hydroxy-nonanoic acid. The possibility that the entire molecule is assembled as a single polyketide with a Baeyer-Villiger oxidation inserting an oxygen into the carbon backbone has been ruled out because C1 of monic acid and C9 ...
In acidic form it is a highly reactive strong acid. In its conjugate base form as a salt it is stable and commonly ion paired with ammonium. In the commercial product Surflon S-111 (CAS 72968-3-88) it is the primary compound present by weight. PFNA is used as surfactant for the production of the fluoropolymer polyvinylidene fluoride.
Ozonolysis of oleic acid is an important route to azelaic acid. The coproduct is nonanoic acid: [20] CH 3 (CH 2) 7 CH=CH(CH 2) 7 CO 2 H} + 4 O 3 → HO 2 C(CH 2) 7 CO 2 H} + CH 3 (CH 2) 7 CO 2 H. Erucic acid is a precursor to brassylic acid, a C13-dicarboxylic acid that is used to make specialty polyamides and polyesters.
Azelaic acid is industrially produced by the ozonolysis of oleic acid. The side product is nonanoic acid. It is produced naturally by Malassezia furfur (also known as Pityrosporum ovale), a yeast that lives on normal skin. The bacterial degradation of nonanoic acid gives azelaic acid. [6]
