Description

(Z)-Whiskeylactone,5-Butyldihydro-4-Methyl-2(3H)-Furanone,(-)-cis-Whiskeylactone is a high-purity, optically active lactone compound prized for its unique organoleptic properties. This compound is a key flavor and fragrance ingredient, imparting the characteristic creamy, coconut, and woody notes associated with aged spirits and gourmet flavors. It is an essential raw material for flavorists and perfumers in the food & beverage, fragrance, and fine chemical industries seeking to create sophisticated, authentic sensory profiles.

Application

• Flavor & Fragrance (F&F) Industry: A premium additive for creating and enhancing flavors with creamy, coconut, lactonic, and woody nuances, particularly in alcoholic beverage flavors (whiskey, rum, wine), dairy flavors, and tropical fruit flavors.
• Food & Beverage: Used in the formulation of flavorings for confectionery, baked goods, dairy products, and premium spirits to replicate the complex aroma of barrel-aged products.
• Perfumery: Serves as a valuable fragrance component in fine perfumes, cosmetics, and personal care products, adding warm, sweet, and milky tonalities to fragrance compositions.
• Aroma Chemicals & Intermediates: Acts as a chiral building block or intermediate in the synthesis of more complex flavor molecules and fine chemicals for research and development.
• Research & Development: Utilized in academic and industrial R&D for studies in organic synthesis, stereochemistry, and sensory science.
