1119-44-4 Usage
Description
3-Hepten-2-one is a ketone derivative that belongs to the family of Acryloyl Compounds. It has a powerful, green grassy, and caraway odor. 3-Hepten-2-one is used as a flavoring and fragrance agent, providing a green note to fruity compositions and a creamy flavor for caraway, passion fruit, and pineapple flavors.
Uses
Used in Flavor and Fragrance Industry:
3-Hepten-2-one is used as a flavoring agent for adding depth and lingering rich after-notes to processed dairy products such as custard, melted butter, creams, and cheeses (Brie, Gorgonzola, and blue cheeses). It also enhances the flavor of fatty nut applications like Brazil nuts and pine nuts.
Used in Dairy Products:
3-Hepten-2-one is used as a flavoring agent to provide a creamy, dairy, waxy, stale milky, blue cheese, and cheese rind taste with a good mouthfeel to dairy products.
Used in Nut Flavoring:
3-Hepten-2-one is used as a flavoring agent to enhance the taste of fatty nuts such as Brazil nuts and pine nuts.
Used in the Production of Heptan-2-one:
3-Hepten-2-one is also used in the production of Heptan-2-one, another compound with various applications.
Occurrence:
3-Hepten-2-one has been reported to be found in various natural sources such as Byrsinoma crassifolia, red and green pepper, capsicum varieties, hop oil, and roasted flbert.
Preparation
By reacting 1-pentyne with acetic anhydride to yield 3-heptyn-2-one, which is then converted to cis-3-hepten-2-one by partial catalytic hydrogenation; the trans-form is probably obtained from trans-2-hexenic acid treated with methyl lithium.

Check Digit Verification of cas no
The CAS Registry Mumber 1119-44-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,1 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1119-44:
(6*1)+(5*1)+(4*1)+(3*9)+(2*4)+(1*4)=54
54 % 10 = 4
So 1119-44-4 is a valid CAS Registry Number.

Enantioselective [4 + 2] cycloaddition of cyclic N-sulfimines and acyclic enones or ynones: A concise route to sulfamidate-fused 2,6-disubstituted piperidin-4-ones

A concise route to valuable sulfamate-fused 2,6-disubstituted piperidin-4-ones or 2,3-dihydropyridin-4(1H)-ones in good yield with high diastereo- and enantioselectivity is presented. The combination of chiral primary amine and o-fluorobenzoic acid efficiently promoted an asymmetric [4 + 2] cycloaddition reaction of N-sulfonylimines and enones or ynones. The cycloaddition reaction between cyclic N-sulfonylimines and ynones is first reported.
A 2-heptanone synthetic method
-
Paragraph 0043, (2017/01/26)
The invention discloses a chemical synthetic method, specifically a method for synthesizing 2-heptanone by using acetone and butyraldehyde as raw materials. According to the invention, acetone and butyraldehyde which used as raw materials undergo a cross aldol condensation reaction under catalysis of solid base, and reaction products further undergo dehydration and catalytic hydrogenation so as to prepare 2-heptanone. The invention has advantages as follows: technological process is shortened by the technology; generation of an acid-containing waste liquid is avoided; generation of by-products is minimized; investment in equipment is reduced; and production costs of the product are decreased.
