trans-2-Decenal Usage And Synthesis

Chemical Properties

clear colorless to light yellow liquid

Chemical Properties

2-Decanal has a powerful waxy, orange aroma.

Occurrence

Reported found in bitter orange peel, blackberry, ginger, butter, mushroom, kiwi, bacon fat, roast beef, beef fat, heated beef fat, bilberries, carrot root, boiled chicken, chicken broth, cranberry press residue, ham, lingonberry, orange, heated pork fat, potato chip, soy bean, boiled mutton, tea, roasted filberts, roasted peanuts and coriander leaf.

Uses

trans-2-Decenal is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff. Trans-2-Decenal Natural (Neat) is a colourless to pale yellow liquid with an orange floral odour. The liquid has a fatty, fried, citrus taste and is a flavouring agent.

Preparation

By reaction of octanal and ethyl vinyl ether and subsequent hydrolysis.

Definition

ChEBI: A decenal containing a double bond at position 2 (the trans-stereoisomer).

Aroma threshold values

Detection: 1 ppb; aroma characteristics at 1.0%: waxy, fatty, earthy, coriander, green, mushroom, aldehydic with a chicken and pork fat nuance.

General Description

trans-2-Decenal is one of the compounds that contribute to the taste and odor problem in drinking water. It was determined in water samples by headspace solid-phase microextraction (SPME) coupled with gas chromatography-mass spectrometry. It also shows strong nematicidal activity.
