General Description
(E)-2-Butenoic acid isobutyl ester, also known as isobutyl crotonate, is a chemical compound with the molecular formula C9H16O2. It is an ester of isobutyl alcohol and (E)-2-butenoic acid. This colorless liquid is commonly used in the fragrance industry as a sweet, fruity, and floral odor enhancer. It is also used as a flavoring agent in the food industry. Isobutyl crotonate is considered to be a non-volatile and non-polar compound, making it useful in various applications such as in the production of cosmetics, perfumes, and as a solvent in some industrial processes. Additionally, it may also have potential applications in the pharmaceutical and agricultural sectors.
Check Digit Verification of cas no
The CAS Registry Mumber 73545-15-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,4 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73545-15:
(7*7)+(6*3)+(5*5)+(4*4)+(3*5)+(2*1)+(1*5)=130
130 % 10 = 0
So 73545-15-0 is a valid CAS Registry Number.

Transannular vs intramolecular insertion reactions of transition metal carbenes: Evaluation of a transannular approach to cyclooctane ring synthesis
Dudones, James D.,Sampson, Paul
, p. 9555 - 9567 (2007/10/03)
The efficacy of closing cyclooctane rings via transannular metal-stabilized carbene insertion reactions within an 11-membered macrocyclic lactone ring was explored. The impact of performing these reactions in a transannular fashion was evaluated via a comparative study of closely analogous intramolecular (but not transannular) processes. Closure of a γ-lactone ring via intramolecular cyclopropanation on a moderately electron-deficient alkene proceeded in good yield under Cu(acac)2 catalysis, whereas analogous transannular cyclopropanation was thwarted by competitive β-hydride migration. In contrast, use of a more electron-rich methoxy-substituted alkene resulted in successful transannular cyclopropanation to afford the desired cyclooctane ring-containing product.
