Description

(S)-γ-Decalactone CAS NO 107797-27-3 is a high-purity, optically active flavor and fragrance lactone characterized by its intense peachy, creamy, and coconut-like aroma. This chiral compound is essential for creating sophisticated, natural-tasting flavor profiles and high-value fragrance compositions where stereochemistry impacts the sensory outcome. It is a critical ingredient for flavorists and perfumers in the food & beverage, fine fragrance, and personal care industries seeking premium, enantiomerically pure materials.

Application

• Flavor Industry: As a key flavoring agent for peach, apricot, cream, butter, coconut, and tropical fruit flavor systems in beverages, dairy products, confectionery, and baked goods.
• Fragrance Industry: Used in fine perfumery to impart creamy, lactonic, and fruity nuances in floral, oriental, and gourmand fragrance compositions for perfumes, lotions, and soaps.
• Food & Beverage Manufacturing: For the enhancement and rounding of natural fruit flavors in juices, yogurts, ice creams, and alcoholic beverages.
• Personal Care & Cosmetics: Incorporated into scented products like shampoos, conditioners, and body creams to provide a pleasant, natural fruity-creamy scent.
• Aroma Chemical Synthesis: Serves as a chiral building block or intermediate in the synthesis of more complex flavor and fragrance molecules.
• Natural Flavor Production: Used in the creation of WONF (With Other Natural Flavors) and natural flavor formulations due to its occurrence in nature.
