Fatty aldehydes

Octanal is the organic compound, an aldehyde, with the chemical formula CH3(CH2)6CHO. A colorless fragrant liquid with a fruit-like odor, it occurs naturally in citrus oils. It is used commercially as a component in perfumes and in flavor production for the food industry. It is usually produced by hydroformylation of heptene and the dehydrogenation of 1-octanol.

Decanal is an organic compound with the chemical formula . A colorless oil, it is classified as an aldehyde.

Nonanal is an organic compound with the chemical formula . It is one of several isomers, all are colorless oil. The nonanals are classified as aldehydes. The linear nonanal is produced commercially by the hydroformylation of 1-octene. It is used as a fragrance.

2-Nonenal is an unsaturated aldehyde. The colorless liquid is an important aroma component of aged beer and buckwheat, and is insoluble in water.

Dodecanal, also known as lauraldehyde or dodecyl aldehyde, is an organic compound with the chemical formula CH3(CH2)10CHO. This colourless liquid is a component of many fragrances. It occurs naturally in citrus oils, but commercial samples are usually produced from dodecanol by dehydrogenation.

Octodecanal is a long-chain aldehyde, with the chemical formula C18H36O (also known as stearyl aldehyde). Octadecanal is used by several species of insect as a pheromone.

Traumatin is a plant hormone produced in response to wound. Traumatin is a precursor to the related hormone traumatic acid.

2-Methylundecanal is an organic compound that is found naturally in kumquat peel oil. This compound smells herbaceous, orange, and ambergris-like. At high dilution it has a flavor similar to honey and nuts. It is a colorless or pale yellow liquid that is soluble in organic solvents such as ether and ethanol. It is used as a fragrance component in soaps, detergents, and perfumes.

Undecanal, also known as undecyl aldehyde, is an organic compound with the chemical formula C10H21CHO. It is an eleven-carbon aldehyde. A colourless, oily liquid, undecanal is a component of perfumes. Although it occurs naturally in citrus oils, it is produced commercially by hydroformylation of decene.

chemical compound

Tridecanal is an organic compound with the formula . A colorless oily liquid, it is the aldehyde derivative of tridecane. It is produced by hydroformylation of 1-dodecene. Hydrogenation of tridecanal gives 1-tridecanol.

6-Nonenal is an organic compound with the formula C2H5CH=CH(CH2)4CHO. Other isomeric nonenal compounds are also known to exist naturally, e.g. 2-nonenal. The cis-isomer of 6-nonenal is often listed as the principal component in the aromas of muskmelon fruits. The trans-isomer is listed as an off-flavor aroma of milk foams, and thought to be a possible polypropylene odorant.
