2349-13-5 Usage
Description
Heptyl Isobutyrate is a synthetic flavoring agent characterized by its woody odor with distinctly herbaceous, sweet undernotes and a sweet, herbaceous, fruity, and slightly warm, floral taste. It is a stable, colorless liquid and is synthesized by the esterification of n-heptanol with isobutyric acid. It has an aroma threshold value of 12 to 13 ppb and is reported to be found in the essential oil of hops.
Uses
Used in Flavor Industry:
Heptyl Isobutyrate is used as a flavoring agent for its characteristic woody odor and sweet, herbaceous, fruity, and slightly warm, floral taste. It is particularly used in flavors for pineapple, pear, and orange, with applications in beverages, ice cream, candy, and baked goods at a concentration of 1–3 ppm.
Used in Fragrance Industry:
Although not explicitly mentioned in the provided materials, Heptyl Isobutyrate, due to its distinct odor and characteristics, can also be used in the fragrance industry for creating various scent compositions.
Preparation
By esterifcation of n-heptanol with isobutyric acid.
Check Digit Verification of cas no
The CAS Registry Mumber 2349-13-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,4 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2349-13:
(6*2)+(5*3)+(4*4)+(3*9)+(2*1)+(1*3)=75
75 % 10 = 5
So 2349-13-5 is a valid CAS Registry Number.

A Phosphonium Ylide as an Ionic Nucleophilic Catalyst for Primary Hydroxyl Group Selective Acylation of Diols

Carbonyl-stabilized phosphonium ylides exhibit great utility in modern organic synthesis, and they are known as an ambident nucleophile at the carbonyl oxygen atom and at the α-carbon atom. However, they have found limited use as catalysts. We focused on the inherent nucleophilicity of the oxygen atom to develop an ionic nucleophilic catalysis, and the phosphonium ylide-catalyzed primary alcohol selective acylation of mixed diols with acid anhydrides has been demonstrated. Mechanistic studies revealed the behavior of a catalyst, which would contribute to the field of ylide chemistry.
