Description

Nonanal has a strong, fatty odor developing an orange and rose note on dilution. It has a fatty, citrus-like flavor. May be synthesized by catalytic oxidation of the corresponding alcohol (n- nonanol) or by reduction of the corresponding acid.

Chemical Properties

n-Nonanal has a strong, fatty odor developing an orange and rose note on dilution. It has a fatty, citrus-like flavor

Chemical Properties

brown liquid

Uses

Nonanal is a flavoring agent that is a colorless or light yellow liquid, with a strong odor resembling an essence of orange and rose. It is soluble in alcohol, most fixed oils, mineral oil, and propylene glycol, but insoluble in glycerin. It is obtained by chemical synthesis. It is also termed aldehyde c-9 and pelargonic aldehyde.

Uses

A component of essential oils, Nonanal possesses a strong fruity odor. Essential oils have varying effects from antibacterial activity to hypolipidemic activity.

Definition

ChEBI: A fatty aldehyde formally arising from reduction of nonanoic acis. Metabolite observed in cancer metabolism.

Preparation

By catalytic oxidation of the corresponding alcohol (n-nonanol) or reduction of the corresponding acid

Aroma threshold values

1 to 8 ppb; aroma characteristics at 1.0%: sweet waxy, orange citrus with oily fatty and melon skin nuances and a slightly lactonic nuance

Taste threshold values

aste characteristics at 2 ppm in 5% sugar and 0.1% CA: aldehydic citrus orange body with waxy and oily melon-like nuances

General Description

Clear brown liquid characterized by a rose-orange odor. Insoluble in water. Found in at least 20 essential oils, including rose and citrus oils and several species of pine oil.

Fire Hazard

1-Nonanal is combustible.

Safety Profile

A severe skin irritant. Combustible liquid. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES.
