colourless liquid | [Chemical Properties]
Dodecanal is a colorless liquid
with a waxy odor; in high dilution, it is reminiscent of violets. Dodecanal occurs in
several citrus oils and has been found in small amounts in essential oils obtained
from several Pinus species. It is used in perfumery in conifer fragrances with fatty,
waxy notes, but also in many other odor types. It is added to aroma compositions
to obtain citrus notes. | [Chemical Properties]
Lauric aldehyde has a characteristic fatty odor reminiscent of violet on dilution and a fatty, woody taste. | [Occurrence]
Reported found in the essential oils of lemon, sweet orange, bitter orange, mandarin, Mexican lime and
petitgrain bigarade and in the turpentine of some varieties of pine. Also reported found in berries, apple, carrot, celery, cucumber,
rutabaga, ginger, wheat bread, cheeses, milk, butter, caviar, fatty fish, roast chicken, cooked beef and pork, hop oil, beer, rum, peanut, mango, kelp, coriander seed and leaf, lovage leaf, buckwheat, cherimoya, mountain papaya, clam, scallop, loganberry and mate. | [Uses]
Dodecanal is a fragrance agent that is found in soaps, perfumes as well as in food flavoring materials. | [Uses]
Dodecyl aldehyde is used as a fragrance agent. It is used as a common ingredient in perfumery. It's end applications include soap, detergent, beauty care product, household product. | [Definition]
ChEBI: Dodecanal is a long-chain fatty aldehyde that is dodecane in which two hydrogens attached to a terminal carbon are replaced by an oxo group. It has a role as a plant metabolite. It is a 2,3-saturated fatty aldehyde, a medium-chain fatty aldehyde and a long-chain fatty aldehyde. It derives from a hydride of a dodecane. | [Preparation]
By oxidation of the corresponding alcohol or reduction of the acid | [Aroma threshold values]
Detection: 0.5 to 1.5 ppb; aroma characteristics at 2.0%: soapy, waxy, aldehydic, citrus, orange rindy with
floral nuances | [Taste threshold values]
Taste characteristics at 2.0 ppm: soapy, waxy, citrus, orange mandarin. | [Synthesis Reference(s)]

Tetrahedron Letters, 17, p. 2503, 1976 | [General Description]
Lauric aldehyde is one of the main aliphatic green volatile compounds in macerated grape cluster stems. It is also one of the key flavor constituents of grapefruit oil. | [Flammability and Explosibility]
Nonflammable | [Synthesis]
Dodecyl aldehyde is synthesized by catalytic dehydrogenation of Dodecanol (Lauryl alcohol).
| [Metabolism]
See monograph on aldehyde C-8* | [Purification Methods]
Convert lauraldehyde to the bisufite addition compound by shaking with saturated aqueous NaHSO3 for 1hour. The precipitate is filtered off, washed with ice cold water, EtOH and ether, then decomposed with aqueous Na2CO3. The aldehyde is extracted into diethyl ether which, after drying and evaporating, gives an oil which is fractionally distilled under vacuum. [Beilstein 1 IV 3380.] |
