626-53-9 Usage
Description
Heptane-2,4,6-trione, also known as diacetyl, is a yellow or greenish-yellow organic compound that belongs to the class of diketones. It is a six-carbon molecule with two carbonyl (C=O) groups attached to adjacent carbon atoms, giving it a buttery or creamy taste and aroma. Diacetyl is found naturally in a variety of foods such as butter, beer, and wine, and is also artificially produced for use in the food industry.
Uses
Used in Food Industry:
Heptane-2,4,6-trione is used as a flavoring agent for its buttery or creamy taste and aroma, enhancing the flavor of various food products.
Used in Beverage Industry:
Heptane-2,4,6-trione is used as a flavoring agent in the production of beer and wine, contributing to their distinct taste and aroma.
However, it is important to note that heptane-2,4,6-trione has been associated with respiratory issues and is a recognized respiratory hazard in the workplace, particularly in industries where it is used in large quantities. As a result, regulations on its use and exposure limits have been implemented in some countries to ensure the safety of workers and consumers.
Check Digit Verification of cas no
The CAS Registry Mumber 626-53-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 626-53:
(5*6)+(4*2)+(3*6)+(2*5)+(1*3)=69
69 % 10 = 9
So 626-53-9 is a valid CAS Registry Number.

Unusual aluminum chloride-assisted conversion of isopropenyl acetate into 3-acetyl- and 3,5-diacetyl-2,6-dimethyl-4H-pyran-4-ones
Novikov,Shestak,Denisenko
experimental part, p. 1600 - 1604 (2011/05/04)
Reflux of isopropenyl acetate with an excess of AlCl3 in 1,2-dichloroethane affords 3,5-diacetyl-2,6-dimethyl-4H-pyran-4-one in 17% yield. The mild acidic cleavage of the latter (2% HCl, 20°C, 16 h) gives 3-acetyl-2,6-dimethyl-4H-pyran-4-one in 87% yield, whereas this reaction under more drastic conditions (17% HCl, reflux, 3 h) gives 2,6-dimethyl-4H-pyran-4-one in 61% yield.
