Description

(2E,4Z,7Z)-Deca-2,4,7-Trienal is a high-purity, unsaturated aliphatic aldehyde characterized by its specific conjugated triene structure. This compound is valued for its role as a key flavor and fragrance intermediate, imparting unique green, fatty, and cucumber-like notes. It is essential for manufacturers in the flavor & fragrance, food, and cosmetic industries seeking to create complex, naturalistic sensory profiles.

Application

• Flavor & Fragrance Industry: A crucial building block for synthesizing complex aroma chemicals and natural-identical flavor compounds.
• Food Flavoring: Used to impart or enhance green, fatty, and fresh vegetable (e.g., cucumber, melon) notes in processed foods and beverages.
• Perfumery: Serves as a valuable intermediate in the creation of fine fragrances, adding unique top or middle notes.
• Cosmetic Ingredients: Employed in the formulation of scented personal care products such as lotions, soaps, and shampoos.
• Chemical Synthesis: Acts as a versatile intermediate in organic synthesis, particularly in Diels-Alder reactions and other transformations involving conjugated diene/triene systems.
• Research & Development: Used in analytical laboratories as a reference standard and in academic or industrial R&D for studying flavor chemistry and reaction mechanisms.
