Beschreibung
Nerol has a fresh, sweet, rose-like odor and a bitter flavor. Nerol may be synthesized from pinene.
Chemische Eigenschaften
Nerol occurs in small
quantities in many essential oils where it is always accompanied by geraniol; its
name originates from its occurrence in neroli oil. Nerol is a colorless liquid with a
pleasant rose-like odor, which, unlike that of geraniol, has a fresh green note.
Nerol undergoes the same reactions as geraniol but cyclizes more readily in the
presence of acids.
Nerol is produced along with geraniol from myrcene in the process described
for geraniol. It can be separated from geraniol by fractional distillation.
Nerol is used in perfumery not only for the same purposes as geraniol,
for example, in rose compositions, to which it lends a particular freshness, but
also in other blossom compositions. In flavor work, it is used for bouquetting citrus
flavors. Technical-grade nerol, often in a mixture with geraniol, is used as an
intermediate in the production of citronellol and citral.
Occurrence

lavender, Mexican linaloe, myrrh, jasmine, Paraguay petitgrain; also reported among the volatile constituents of currant aroma;

Verwenden
Nerol is an isomer of Geraniol (G367000), used in the synthesis of insect repellant. It is also used in the synthesis of Angelicoin A and Herecinone J, which inhibit collagen-induced platelet aggregat
ion.
Definition
ChEBI: The (2Z)-stereoisomer of 3,7-dimethylocta-2,6-dien-1-ol. It has been isolated from the essential oils from plants like lemon grass.
synthetische
From pinene.
Allgemeine Beschreibung
The antifungal efficacy of nerol (
cis-3,7-Dimethyl-2,6-octadien-1-ol), against
Aspergillus flavus, was studied.
Sicherheitsprofil
Moderately toxic by
intramuscular route. Mildly toxic by
ingestion. A skin irritant. When heated to
decomposition it emits acrid smoke and
irritating fumes.
