Trans-2-octenal, also called (E)-2-Octenal, is a colorless to slightly yellow liquid at room temperature and pressure, with a special smell of aldehyde. Trans-2-octenal belongs to unsaturated aldehyde compounds, which have both the common properties of aldehyde groups and the chemical reactivity of double bonds. The aldehyde groups in its structure can be converted into corresponding carboxylic acid derivatives under the action of oxidants, and can also generate corresponding allyl alcohol derivatives under the action of reducing agents. This substance is often used as a raw material for organic synthesis and fine chemical production, and can be used in the preparation of cherry, dairy products, nuts, and meat flavors.
Trans-2-octenal is insoluble in water, but can be miscible with common organic solvents. This substance is a relatively active organic compound with flammability and certain chemical reactivity. This substance can undergo Michael addition reaction with various nucleophilic reagents under alkaline conditions to derive a variety of fatty aldehyde compounds.
Trans-2-octenal may be one of the main factors causing the smell of California long-grain rice.
Trans-2-octenal is an excellent modifier of floral aromas. The fatty aroma of citrus, especially orange, nuts, especially hazelnuts. Use: add fresh cucumber, green herbs and banana top notes.
Trans-2-octenal can be used as an organic synthesis intermediate. With the help of the double bond and the diverse transformation properties of the aldehyde group in its structure, it can be used to synthesize a variety of organic functional molecules containing octane.
