Description

(2E,6Z)-2,6-Octadienal CAS NO 76917-23-2 is a high-purity, unsaturated aliphatic aldehyde characterized by its distinctive, fresh, and green odor profile. This compound is a key intermediate and fragrance ingredient valued for its ability to impart natural, leafy, and cucumber-like top notes. It is essential for manufacturers in the flavor and fragrance industry, as well as for researchers in organic synthesis and aroma chemistry.

Application

• Fragrance Formulation: A primary building block for creating fresh, green, and natural olfactory accords in fine perfumery, personal care products, and household cleaners.
• Flavor Enhancement: Used to replicate or enhance fresh, cucumber, melon, and green vegetable notes in food and beverage flavorings.
• Organic Synthesis: Serves as a versatile dienal intermediate for Diels-Alder reactions and the synthesis of more complex aroma chemicals and pharmaceutical precursors.
• Aroma Chemical Production: A key raw material for the manufacture of other valuable fragrance compounds through hydrogenation, oxidation, or condensation reactions.
• Research & Development: Used in academic and industrial R&D for studying reaction mechanisms, olfactory receptor interactions, and developing new synthetic methodologies.
