22428-91-7 Usage
Description
2-Formyl-3-butanone, commonly known as diacetyl, is an organic compound with the chemical formula C5H8O2. It is a yellowish liquid characterized by a strong buttery odor and is primarily recognized for its use as a flavoring agent in food products. Diacetyl is also a natural byproduct of fermentation processes and can be found in certain foods such as butter, cheese, and wine. However, it has been linked to respiratory and skin irritation, and there are concerns about its potential to cause lung disease when inhaled in high concentrations. As a result, the use of diacetyl in food products has been subject to regulation and reduction in recent years.
Uses
Used in Food Industry:
2-Formyl-3-butanone is used as a flavoring agent for its distinctive buttery aroma and taste, enhancing the flavor profiles of various food products.
Used in Fermentation Processes:
Diacetyl is a natural byproduct of fermentation and contributes to the characteristic flavors found in foods such as butter, cheese, and wine, adding depth and complexity to their taste.
However, due to health concerns associated with diacetyl, its use in food products has been regulated and reduced, leading to the exploration of alternative flavoring agents that can replicate its buttery notes without the associated risks.
Check Digit Verification of cas no
The CAS Registry Mumber 22428-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,2 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22428-91:
(7*2)+(6*2)+(5*4)+(4*2)+(3*8)+(2*9)+(1*1)=97
97 % 10 = 7
So 22428-91-7 is a valid CAS Registry Number.

Cassis and Green Tea: Spontaneous Release of Natural Aroma Compounds from β-Alkylthioalkanones

, (2021/10/19)
In depth headspace analysis of the slow degradation of β-alkylthioalkanones in ambient air led to the discovery of a novel δ-cleavage pathway, by which β-mercaptoketones are released. Since β-mercaptoketones are potent natural aroma compounds occurring in many fruits, herbs and flowers, the discovery of an enzyme-independent molecular precursor for this class of high-impact molecules is of practical importance. Moreover, the formation of β-diketones and aldehydes by concomitant oxidation at the α-sulfur-position enhances the versatility of this class of aroma precursors. A mechanistic model is proposed which suggests that the oxidative degradation occurs through a novel Pummerer-type rearrangement of initially formed persulfoxides.
Efficient synthesis of an A-B-C-tricycle fragment for a structural model of tolyporphin

experimental part, p. 89 - 100 (2010/11/18)
An efficient stereocontrolled synthesis of an A-B-C-tricycle fragment 7 for a structural model of tolyporphin 3 is described. All the rings were prepared from readily available starting materials. One of the two key steps is a selective ring-opening reaction of the lactone cycle in bicyclolactam-lactone 17 to cyanopyrrolidone 18, which introduces the chirality into synthetic compounds. The other key step is the combination of A ring with B-C-bicycle via a two-time Eschenmoser sulfide contraction. A-B-C-tricycle fragment 7 allows a new approach toward tolypophin compounds and other uroporphinoids.
