Pentadecanolide(Cat No.:R060186)is a naturally occurring macrocyclic lactone with the molecular formula C15H28O2. It features a 15-membered ring formed by the intramolecular esterification of a hydroxy acid, giving it a distinct musky odor. Widely used in the fragrance and flavor industry, pentadecanolide imparts warm, animalic, and creamy notes to perfumes and food products. It is found in some plant oils and animal secretions and is prized for its excellent fixative properties. Its large ring structure also makes it of interest in supramolecular chemistry and drug delivery research due to its host-guest capabilities.
