Description

(Z)-Oak-Lactone,5-Butyldihydro-4-Methyl-2(3H)-Furanone,(+)-cis-Whiskeylactone is a high-purity, naturally-derived lactone compound prized for its unique organoleptic properties. This compound is a key flavor and fragrance ingredient, imparting characteristic woody, coconut, and sweet notes essential for creating authentic and sophisticated sensory profiles. It is a critical raw material for flavor and fragrance houses, food and beverage manufacturers, and producers of premium spirits and alcoholic beverages seeking to enhance or standardize their product's aroma and taste.

Application

• Flavor & Fragrance (F&F) Industry: As a primary building block for creating and enhancing woody, creamy, and coconut-like notes in fine perfumes, cosmetics, and personal care products.
• Food & Beverage Flavors: Used to impart authentic oak, coconut, and sweet nuances in dairy products, confectionery, baked goods, and non-alcoholic beverages.
• Spirits & Alcoholic Beverages: Critical for replicating or enhancing the complex barrel-aged character in whiskies, wines, brandies, and other aged spirits, contributing to the desired "oaky" flavor profile.
• Tobacco Flavoring: Employed to add sweet, woody notes to tobacco products for a more rounded and appealing flavor.
• Aromatherapy & Home Scents: A valuable component in essential oil blends, candles, and diffusers for creating warm, comforting, and natural woody aromas.
• Chemical Synthesis: Serves as a chiral intermediate or starting material in the synthesis of more complex flavor molecules and fine chemicals.
