626-53-9 Usage

General 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 commonly used as a flavoring agent and has a buttery or creamy taste and aroma. Chemically, it is a six-carbon molecule with two carbonyl (C=O) groups attached to adjacent carbon atoms. 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. However, it 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.

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.
