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
white crystalline low melting solid
Chemical Properties
ω-Pentadecalactone has an extraordinarily persistent, musk-like odor.
Occurrence
Originally reported found in the essential oil from angelica roots.
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.
General Description
Pentadecanolide is one of the major components, isolated from the root of Angelica archangelica L., species. It is a synthetic musk, which exists as a widespread contaminant in the environment.
Flammability and Explosibility
Nonflammable
Trade name
Macrolide® (Symrise), Exaltolide®, Exaltolide®Total (Firmenich),
Pentalide (Soda Aromatic).
Purification Methods
It has been recrystallised from MeOH (4 parts) at -15o. [Hundieck
