herbaceous, sweet undernotes and a sweet herbaceous, fruity, and
slightly warm, floral taste.
Synthesis: By esterification of n-heptanol with isobutyric acid.
Chemical Properties
Heptyl isobutyrate has a characteristic woody odor with distinctly herbaceous, sweet undernotes and a sweet, herba- ceous, fruity and slightly warm, foral taste.
Occurrence
Reported found in the essential oil of hops
Uses
Heptyl Isobutyrate is a synthetic flavoring agent that is a stable,
colorless liquid of fruity odor. it should be stored in glass or tin con-
tainers. it is used in flavors for pineapple, pear, and orange with
applications in beverages, ice cream, candy, and baked goods at
1–3 ppm.
Preparation
By esterifcation of n-heptanol with isobutyric acid.
Aroma threshold values
Detection: 12 to 13 ppb.
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.
