Cyclopentadecanolide is a natural macrolide lactone and a synthetic musk.
Natural occurrence
Cyclopentadecanolide occurs in small quantities in angelica root essential oil and is responsible for its musklike odor.[1]
Production
Cyclopentadecanolide is produced synthetically by ring expansion of cyclododecanone. Another synthesis route is the depolymerization of polyesters of 15-hydroxypentadecanoic acid.[1]
Uses
Cyclopentadecanolide is used as a musklike perfume fixative in fine fragrances and as a flavoring agent.[2] It is a substitute for the extremely expensive animal musk.[1]
