Description

(3E,6Z)-3,6-Nonadienal is an unsaturated aliphatic aldehyde characterized by its distinct green, cucumber-like, and melon rind aroma. This compound matters as a high-value fragrance and flavor intermediate, prized for its ability to impart fresh, natural green notes to complex formulations. It is primarily needed by manufacturers in the flavor and fragrance, food and beverage, and personal care industries seeking to create sophisticated, natural-smelling products.

Application

• Fragrance Formulation: A key ingredient for creating fresh, green, and cucumber-like top notes in fine perfumes, colognes, and body care products.
• Flavor Creation: Used as a flavoring agent to impart natural melon, cucumber, and green vegetable nuances to beverages, confectionery, and savory food products.
• Aroma Chemical Synthesis: Serves as a valuable chiral building block or intermediate in the synthesis of more complex fragrance molecules.
• Personal Care Products: Incorporated into soaps, shampoos, lotions, and detergents to provide a fresh, clean scent profile.
• Household Products: Used in air fresheners, fabric softeners, and cleaning agents for its refreshing green character.
• Research & Development: Utilized in academic and industrial R&D for studying olfactory receptors, organic synthesis pathways, and structure-odor relationships.
