Contents

Occurrence and production

Cyclopentadecanolide occurs in small quantities in angelica root essential oil and is responsible for its musklike odor. [3]

Cyclopentadecanolide is produced by ring expansion of cyclotetradecanone. Another synthesis route is the depolymerization of polyesters of 15-hydroxypentadecanoic acid. [3]

Uses

Cyclopentadecanolide is used as a musklike perfume fixative in fine fragrances and as a flavoring agent. [4] It is a substitute for the extremely expensive animal musk. [3]
