Description

4,7,9-Megastigmatrien-3-One is a high-purity, naturally-derived aromatic ketone known for its potent and complex organoleptic profile. This compound is valued for its significant contribution to the flavor and fragrance of tobacco, as well as its role in creating sophisticated, woody, and tobacco-like notes in fine perfumery. It is an essential ingredient for flavorists and perfumers in the flavor and fragrance (F&F) industry seeking to enhance product authenticity and depth.

Application

• Tobacco Flavoring: A key component for replicating and enhancing the natural, rich aroma of cured tobacco in cigarettes, cigars, and smokeless tobacco products.
• Fine Fragrance: Used as a base note to impart warm, dry, leathery, and woody accords, adding complexity and longevity to perfumes and colognes.
• Functional Fragrances: Incorporated into air care products, detergents, and household cleaners to provide a distinctive, masculine, or sophisticated scent profile.
• Food & Beverage Flavors: Employed in trace amounts to create nuanced, smoky, or dried fruit notes in certain specialty food and beverage applications.
• Aroma Chemicals & Intermediates: Serves as a valuable building block or reference standard in the synthesis and research of other complex aroma molecules.
