Description

(-)-Fenchone CAS NO 7787-20-4 is a naturally occurring bicyclic monoterpene ketone, serving as the principal aromatic component of fennel oil. This compound matters for its distinct camphoraceous, earthy, and slightly sweet odor profile, making it a valuable and versatile building block in flavor and fragrance creation. Industries that need it include manufacturers of fine fragrances, cosmetics, food flavorings, and advanced chemical synthesis, where it acts as a key chiral intermediate.

Application

• Fragrance & Perfumery: A core ingredient for imparting fresh, woody, and camphoraceous notes in fine fragrances, soaps, and detergents.
• Flavoring Agent: Used in the formulation of food and beverage flavors, particularly to replicate or enhance earthy, herbal, and licorice-like taste profiles.
• Cosmetics & Personal Care: Employed as a fragrance component in lotions, creams, and other cosmetic products for its distinctive scent.
• Chemical Synthesis: Serves as a crucial chiral starting material or intermediate in the synthesis of more complex organic molecules for pharmaceuticals and agrochemicals.
• Aromatherapy: Utilized in essential oil blends for its purported grounding and clarifying aromatic properties.
• Research & Development: Used in academic and industrial laboratories as a standard or reagent in organic chemistry and analytical studies.
