| Description |
Nonanoic acid (also known as pelargonic acid; chemical formula: CH3 (CH2)7COOH) is a kind of organic carboxylic acid compound. It is naturally existed in the oil of pelargonium in the form of esters. It is commonly used in conjunction with glyphosate which is a kind of non-selective herbicide in order to obtain a quick burn-down effect in the control of weeds in turfgrass. It is also a potent antifungal agent which can inhibit spore germination and mycelial growth of pathogenic fungi. Its synthetic esters, such as methyl nonanoate can be used as flavorings. Moreover, it can also be used in the preparation of plasticizers and lacquers. It can also be potentially used for the treatment of seizures. |

| Definition |
ChEBI: A C9 straight-chain saturated fatty acid which occurs naturally as esters of the oil of pelargonium. Has antifungal properties, and is also used as a herbicide as well as in the preparation of plasticisers and lacquers. |
| Uses |
In the production of hydrotropic salts (hydrotropic salts form aqueous solutions which dissolve sparingly soluble substances to a greater extent than water); in the manufacture of lacquers, plastics. |
| Agricultural Uses |
Herbicide, Fungicide: Pelargonic acid occurs naturally in many plants and animals. It is used to control the growth of weeds and as a blossom thinner for apple and pear trees. It is also used as a food additive; as an ingredient in solutions used to commercially peel fruits and vegetables |
| Trade name |
CIRRASOL®-185A; ECONOSAN®; EMERY® 202 (mixture with n-octoic acid); EMFAC®-1202; HEXACID® C-9; PELARGON®; SCYTHE®; WEST AGRO ACID SANITIZER® |
| Safety Profile |
Poison by intravenous route. Moderately toxic by ingestion. A severe skin and eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes. |
| Purification Methods |
Esterify the acid with ethylene glycol and distil the ester. (This removes dibasic acids as undistillable residues.) The acid is regenerated by hydrolysing the ester in the usual way and is distilled in vacuo. [Beilstein 2 IV 1018.] |
