Description

trans-2-Dodecenal is a high-purity, unsaturated aliphatic aldehyde characterized by its distinct fatty, citrus-like aroma. This compound serves as a versatile and valuable intermediate in the synthesis of fine chemicals, flavors, and fragrances. It is primarily sought after by manufacturers in the flavor & fragrance, agrochemical, and pharmaceutical industries for its role in creating complex odor profiles and as a building block for specialty molecules.

Application

• Flavor & Fragrance (F&F) Industry: A key component and intermediate for creating citrus, fatty, and waxy notes in perfumes, cosmetics, and food flavorings.
• Agrochemical Synthesis: Used as a precursor or intermediate in the production of certain pesticides and pheromones.
• Organic Synthesis: Serves as a valuable building block for synthesizing more complex organic molecules, including pharmaceuticals and specialty chemicals, via reactions like aldol condensation or reduction.
• Research & Development: Employed as a standard or reagent in chemical research, particularly in studies involving lipid oxidation, aroma chemistry, and organic reaction mechanisms.
