Description and Uses

4-Dodecanolide was one of the organic compounds from meat charbroiling operations studied. Finds some use in perfume compositions for fatty-fruity topnotes and long tenacity, e.g., in heavy floral fragrances. It is also used in combination with newer synthetic musks to produce exceptional tenacity and lasting sweetness in powdery and floral types. Used in flavour compositions, mainly in Butter, Butterscotch, Coconut, Tutti-frutti, Maple, Nut, Peach, Pineapple, etc.
