Description
Ethyl nonanoate is a clear, colorless liquid with a slightly fatty, oily, nutty, fruity odor reminiscent of cognac with a rosy-fruity note. It is a synthetic flavoring agent and a fatty acid ethyl ester of nonanoic acid. It is practically insoluble in water and is miscible with alcohol and propylene glycol. Ethyl nonanoate is used as an internal standard to monitor the solid-phase micro-extraction fiber extraction integrity and efficiency in the separation and quantification from various alcoholic beverages.
Uses
Used in Flavor Industry:
Ethyl nonanoate is used as a synthetic flavoring agent for imparting a fruity, estry, green, waxy, and fatty taste with banana and tropical nuances to various food products. It is used in flavors such as apple, pear, and cognac with applications in beverages, ice cream, candy, and alcoholic beverages at 4-20 ppm.
Used in Beverage Industry:
Ethyl nonanoate is used in the production method of blueberry health-care vinegar containing lactic acid bacteria powder, enhancing the flavor and aroma of the final product.
Used in Perfume Industry:
Ethyl nonanoate is used as a chemical intermediate in the formulation of perfumes, contributing to its fruity and rosy-fruity aroma.
Used in Chemical Industry:
Ethyl nonanoate serves as a chemical intermediate in the synthesis of various compounds and products in the chemical industry.
Occurrence:
Ethyl nonanoate is naturally found in a variety of fruits, such as pineapple, banana, plum, and apple, as well as in Parmesan cheese, milk, beer, and various alcoholic beverages like cognac, rum, whiskey, and grape wines. It is also reported to be present in plum and pear brandy, wheaten bread, beef, corn oil, and elderberry.
Preparation
By distillation of pelargonic acid and ethyl alcohol in toluene in the presence of small amounts of muriatic acid (HCl);
also by hydrogenation of oenanthylidene acetate in the presence of Ni at 180°C.
Safety Profile
Mildly toxic by
ingestion. A skin irritant. Combustible
liquid. When heated to decomposition it
emits acrid smoke and irritating fumes
Check Digit Verification of cas no
The CAS Registry Mumber 123-29-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 123-29:
(5*1)+(4*2)+(3*3)+(2*2)+(1*9)=35
35 % 10 = 5
So 123-29-5 is a valid CAS Registry Number.

Divergent Synthesis of α-Fluorinated Carbonyl and Carboxyl Derivatives by Double Electrophilic Activation of Amides
Dubart, Amaury,Evano, Gwilherm
supporting information, p. 8931 - 8936 (2021/11/17)
A straightforward and divergent entry to α-fluorinated carbonyl and carboxyl derivatives is reported. Upon activation of amides with triflic anhydride and a 2-halo-pyridine and subsequent trapping of the resulting keteniminium ions with nucleophiles followed by a second electrophilic activation with NFSI and final hydrolysis, a range of amides can be transformed to α-fluorinated ketones, esters, and amides under mild conditions. Moreover, this reaction can be performed to yield enantioenriched products with a traceless chiral auxiliary.
Hydroethoxycarbonylation of α-olefins at low pressure of carbon(II) oxide in the presence of the PdCl2(PPh3)2–PPh3–AlCl3 system

High catalytic activity of the PdCl2(PPh3)2–PPh3–AlCl3 system containing AlCl3 as promotor has been demonstrated in the reaction of hydroethoxycarbonylation of hexene-1 and octene-1 at low pressure of carbon(II) oxide (≤25 atm). The reaction yields linear and branched products. The optimal conditions of the process have been elaborated. The target products yield is 84.6–93.8%.
