Cyclopentadecanolide Usage And Synthesis

Chemical Properties

white crystalline low melting solid

Chemical Properties

Cyclopentadecanolide occurs in small quantities in, for example, angelica root oil. It forms colorless crystals (mp 37–38°C) with a delicate, musk-like odor.

Chemical Properties

ω-Pentadecalactone has an extraordinarily persistent, musk-like odor.

Occurrence

Originally reported found in the essential oil from angelica roots.

Uses

Pentadecanolide is a monomer used to make PGA-co-pentadecalactone polymers to be used in the development of directly compressed prolonged release tablets of slightly soluble drugs such as ketoprofen.

Uses

Pentadecanolide may be used for the synthesis of poly(pentadecanolide) (PPDL) by Novozyme 435 catalyzed ring-opening polymerization. It may be employed as starting reagent for the synthesis of terminally-branched iso-fatty acids (iso-C₁₅-C₁₇).

Uses

As a fixative in perfumery.

Definition

ChEBI: Cyclopentadecanolide is a macrolide.

Preparation

The main industrial syntheses start from compounds produced from cyclododecatriene: either by ring expansion of cyclododecanone or by depolymerization of polyesters of 15-hydroxypentadecanoic acid (from 1,12-dodecanediol).

Aroma threshold values

Detection: 1 to 4 ppb

Taste threshold values

Taste characteristics at 75 ppm: vanilla bean, powdery helioropine, creamy and licorice.
