Basic Info
(E)-2-Decenal, also known as trans-2-decenal, is an unsaturated fatty aldehyde organic compound with a molecular formula of C₁₀H₁₈O (molecular weight 154.25). Its structural feature is that the second and third carbon atoms of the decane carbon chain form a trans-configuration (E-form) double bond, and the aldehyde group (-CHO) is located on the second carbon atom at the end of the double bond. This trans-decenal structure gives it specific chemical activity and spatial configuration, which is the key to distinguishing it from cis isomers and other positional isomers.
In terms of physical properties, (E)-2-decenal usually appears as a light yellow to yellow liquid with a boiling point of 229°C (normal pressure) or 78–80°C (3 mmHg reduced pressure conditions), a density of about 0.841 g/mL (25°C), and a flash point of 205 °F. It is insoluble in water, but soluble in ethanol, most non-volatile oils and organic solvents (such as chloroform and ethyl acetate). It has a sweet orange aroma with a distinct waxy smell, which is directly related to the long-chain aldehyde group in its molecular structure.

1. Food flavoring Additives
(E)-2-Decenal is a key ingredient in food flavors, mainly giving citrus fruits (such as sweet orange, peach, and apricot) fruity and waxy aromas. Its aroma threshold is low, and a small amount of addition can significantly enhance the flavor level. According to international standards (FEMA 2366), its usage in soft drinks, ice cream, candy, and baked goods is 3.4 mg/kg, 6.0 mg/kg, 9.0 mg/kg, and 9.0 mg/kg, respectively, and it is recognized as a safe flavor by China’s “Food Additive Usage Standard” (GB2760).
2. Wine Flavor Regulator
In wine and spirits, (E)-2-Decenal and its derivatives (such as trans-4,5-epoxy-(E)-2-decenal) significantly affect the aroma balance. Studies have shown that its sensory threshold in wine is as low as 60 ng/L, and when the concentration increases, it will transform the fresh fruit aroma into cooked fruit or vegetable/nut aroma (such as green hazelnut flavor). The threshold in spirits is higher (400 ng/L), but the concentration can reach 2.4 μg/L, which directly contributes to the oily feeling and complex aroma levels.
3. Daily Chemical Flavor Blending
(E)-2-Decenal is widely used in daily chemical products such as perfumes and detergents, and belongs to the “aldehyde-flavor” fragrance. Its sharp green and fatty aroma can enhance the freshness of floral notes (such as jasmine and lily of the valley), and synergize with citrus essential oils (bergamot and sweet orange) to produce unique rhymes. Commercial products require a purity of ≥92%, and the density and refractive index must meet international standards (FCC IV).
4. Grain Processing and Liquor Brewing
In liquor brewing, aldehydes produced by grain cooking (such as (E,E)-2,4-decadienal) are the core components of “grain aroma”. (E)-2-Decenal homologues contribute grass, malt and fat aromas, affecting the style of the wine. Mixing multiple grains (sorghum, millet, quinoa) can increase the diversity of aldehydes. For example, the aldehyde content of millet is the highest when it is steamed, providing rich precursors for liquor.
5. Synthesis of Pharmaceutical Intermediates
As an organic synthesis intermediate, (E)-2-Decenal is used to prepare drug molecules. Its α,β-unsaturated aldehyde structure is easy to participate in reduction, coupling and other reactions to synthesize high value-added compounds. The existing process is prepared by condensation-decarboxylation of n-octanal and ethyl 3-oxopropionate, with a yield of 87%, avoiding precious metal catalysts and reducing costs.
6. Environmental and Ecological Research
(E)-2-Decenal is used as an allelopathic substance in marine ecology to inhibit the growth of phytoplankton. Experiments show that a concentration of 3–5 mg/L can destroy the synthesis of photosynthetic pigments of algae (such as Prorocentrum donghaiense) and affect the structure of aquatic communities. Related research provides ideas for red tide prevention and control.
