Description

Whiskey Lactone is a high-purity flavor and fragrance compound, specifically the cis isomer of 5-butyl-4-methyldihydro-2(3H)-furanone. This compound is prized for its distinctive, warm aroma of oak, coconut, and sweet spices, which is essential for replicating the complex character of aged spirits and gourmet flavors. It is a critical ingredient for flavorists and perfumers seeking to create authentic, high-end sensory profiles. Primary industrial users include manufacturers in the flavor & fragrance, food & beverage, and specialty chemical sectors.

Application

• Flavor Creation: A key component in formulating flavors for whiskey, bourbon, rum, and other aged spirits, as well as in dairy, nut, and tropical fruit flavor systems.
• Fragrance Composition: Used as a heart note in perfumery to impart warm, woody, and lactonic nuances in fine fragrances, personal care, and home care products.
• Food & Beverage Enhancement: Employed to add depth and matured character to alcoholic beverages, baked goods, confectionery, and savory applications.
• Aroma Chemical Synthesis: Serves as a valuable intermediate or reference standard in the synthesis of more complex aroma molecules.
• Tobacco Flavoring: Used to enhance and round off the flavor profile of tobacco products.
